The Lost Bitcoin is the second book in Sutton Lewis’ Legends Unearthed series of children’s adventure stories. We join Sam, his sister Riley, and their best friends Ava and Jonah on a flight to London. As the plane approaches Heathrow, Sam has a new adventure lined up for the team –- to find the computer a woman named Hannah Collins threw out five years previously, with private keys to fifteen thousand Bitcoin now worth a billion and a half dollars. The hard drive ended up in a garbage dump in the south of London. Hannah Collins has been trying to get permission to search the dump for years, but someone in the city government keeps blocking her. Sam is determined to find that hard drive in the forty acres of active landfill before the dump’s toxic gases destroy it forever. But will they accomplish this mission?

What an adventure! The Lost Bitcoin was so immensely captivating that I read it in one sitting. I liked how Lewis Sutton transposed his fascination with the real fact of the lost hard drive loaded with Bitcoin into this wonderful story. I enjoyed revisiting Westminster Abbey, the Houses of Parliament, the British Museum, Harrods, the Tower of London, and other London landmarks. The illustrations were admirable, and the humor was hilarious; the glitter bombing and ego storage vault were my favorites. I look forward to reading the prequel and the upcoming sequel, and highly recommend this fabulous story for middle-school children who are curious about technology and love adventures.

Sometimes the best treasure hunts begin with something that looks completely ordinary. In Legends Unearthed: The Lost Bitcoin by Sutton Lewis, friends Sam, Riley, Ava, and Jonah travel to London with an unusual mission. Years earlier, accountant Hannah Collins accidentally threw away a hard drive containing the private keys to fifteen thousand Bitcoin. She has tried to recover it ever since, but getting permission to search the enormous landfill has proved nearly impossible. The group believes they can succeed where others have failed. Armed with research and some impressive homemade technology, including a six-wheeled rover nicknamed Trash Panda, they set out to locate the missing device. Their quest takes them from famous London attractions to a massive garbage dump and soon puts them in the path of Reginald Pemberton-Smythe, a local official with his own interest in the fortune. Can four determined kids recover a lost digital treasure before someone else gets to it first?

Legends Unearthed: The Lost Bitcoin by Sutton Lewis was an interesting read. I enjoyed the friendship between Sam, Riley, Ava, and Jonah, especially because each brings something different to their adventures. The writing is descriptive, and there is plenty of humor mixed in. The story also moved at a good pace. I think this would be a fun choice for a school or library book club for older kids. There’s quite a bit they could talk about afterward, especially teamwork, inventions, and cryptocurrency. They could even learn more about Bitcoin or come up with their own creation for finding something lost. The illustrations at the beginning of each chapter were appealing, and the pictures scattered throughout added a lot of detail. Young readers who enjoy mysteries, technology, funny moments, and treasure hunts should have fun with this book. I can easily see this series finding a place in schools and libraries everywhere.

Legends Unearthed: The Lost Bitcoin by Sutton Lewis is the second adventure of four young friends. When Sam, Riley, Ava, and Jonah read about the hard drive that was accidentally thrown away some five years ago in London, containing Bitcoin, they are determined to visit the landfill in London where it is believed to be buried, find the hard drive, and return it to its rightful owner. Having organized for their families to “win” a trip to London, they all set off for a wonderful family adventure. In between visiting the Tower of London, Westminster Abbey, Stonehenge, and other iconic landmarks, the friends scout out the landfill with their self-designed Trash Panda, a mobile rover, and their drone, Sky Fang. They are not the only ones seeking the hard drive, though, and they must fend off the devious Reginald Pemberton-Smythe, the head of the local council who has his own plans for the Bitcoin, plans that should see him regain his place in history as the rightful Plantagenet King of England.

Legends Unearthed is good old-fashioned fun, much in the manner of the iconic movie Home Alone. The images of Reginald Pemberton-Smythe fending off the attacks of paintballs and glitter bombs delivered by the ingenious Trash Panda and Sky Fang will live long in my memory. I know this book is intended for a young reading audience, but it really does do readers a world of good to sit down with a book that is a sheer fun romp, which this one certainly is. The group's visit to Harry Potter World, and the situations and especially the banter that ensued, was a highlight of their tourist visits for me. I did enjoy the effort Sutton Lewis put into developing and exploring the different personality quirks of the four friends as well as their parents. I see that their adventures are not finished yet, and I look forward to the next exciting story. I highly recommend this book.

If you’re looking for a thrilling adventure, Sutton Lewis’ Legends Unearthed: The Lost Bitcoin delivers, as Sam Vasquez, Ava Delgado, Riley Vasquez, and Jonah Park travel to London. Instead of just sightseeing, these four quick-witted kids use their vacation to secretly track down a discarded hard drive loaded with thousands of Bitcoins, which ended up in a South London landfill years ago. They engineer specialized tech, including a custom search rover and a tracking drone, to pull the digital fortune out before the landfill conditions destroy it. Standing right in their way is council leader Reginald Pemberton-Smythe, a crooked official trying to block the search so he can pocket the billion-dollar prize. When he sneaks into their rental home and steals the drive, the friends cook up a creative counter-strategy using media cameras to catch him red-handed. It has you turning the pages to see if they can outmaneuver their adult rival, protect their host property, and return the treasure to its owner. 

Sutton Lewis’ Legends Unearthed: The Lost Bitcoin is a fast-paced middle-grade mystery blending friendship, humor, and creative problem-solving. The characters really shine because each one brings something unique to the table, from tactical logistics and engineering skills to deep research and funny commentary. Using a landfill as the core setting transforms a classic treasure hunt into a modern tech caper, where the danger of decaying equipment and environmental gases keeps the stakes high. The main plot is engaging because it pits youthful teamwork against unfair authority. I loved how the pacing picks up once the kids switch from tech exploration to setting an inventive media trap, using press photographers to target the villain’s ultimate weakness: his fear of public humiliation. The writing style keeps things light and entertaining during family scenes while maintaining true suspense during the high-tech heist. It’s a great choice for young readers who love fascinating gadgets, teamwork, and seeing a smug villain get what’s coming to him.

In Legends Unearthed: The Lost Bitcoin by Sutton Lewis, our four heroes – Sam, Ava, Riley, and Jonah – are back for another adventure. They’ve managed to get their families to go on a family holiday to London, though sightseeing is the last thing on their minds. Behind all the museum trips and tourist stops, the kids are secretly hunting for a discarded hard drive buried somewhere in a South London landfill. That tiny drive holds fifteen thousand Bitcoin, a fortune someone accidentally threw away years ago and left rotting under piles of trash. Armed with homemade rovers and drones, the crew has to navigate a dangerous dump site while staying one step ahead of a local official who's just as determined to get his hands on the prize. Who will get there first?

Legends Unearthed: The Lost Bitcoin by Sutton Lewis is a lot of fun, and the premise alone had me hooked before I'd even finished the first chapter. Sutton clearly did his homework on the real lost Bitcoin story that inspired it, and that grounding gives the whole adventure a nice sense of plausibility, even as the kids pull off increasingly outrageous stunts. The parents being completely oblivious while their kids run secret midnight missions right under their noses is funny, and it never gets old. What really carries the book, though, is the banter between the four leads. They feel like real friends, bickering and teasing but always pulling together when it counts. Sutton also does a good job of putting London's polish against the mess and danger of the landfill, and that contrast keeps things visually interesting throughout. It's a fun, clever read, and I'd recommend it to anyone who likes their adventure stories with a bit of tech smarts and a lot of heart. As it’s the second book in the series, I would recommend reading the first one to get a feel for the characters.
