Sergeant Wolfe has an unexplained death on his hands – Sarah Elizabeth Grahams, who spent time at the Institute. As Seth is drawn toward the Institute in his bid to find her killer, the local teens take matters into their own hands. But their journey is dangerous as they uncover secrets no one was meant to find and the only person they can trust is Seth Wolfe. Can they solve Sarah’s murder? What’s really going on at the Orbriallis Institute? And did it have anything to do with a young boy’s disappearance?

The Orbriallis Institute by Charlotte Zang and Alex J. Knudsen concludes the Lost Grove series. I read the first book, and this is just as gripping and eerie. It’s a story that will keep you hooked, reading until the very last page as your mind begs for the answers to the mysteries in this book and the unanswered ones from the first part. It is action-packed all the way, with plenty of spooky twists and turns to keep you invested. The character development is second to none as the characters from the first book continue to evolve. If you like eerie supernatural/horror stories with plenty of twists and mystery, this is the book for you but it should not be read as a standalone – it is part of a series that should be read in order. Another fantastic offering from two clearly talented authors and incredibly enjoyable.

Charlotte Zang and Alex J. Knudsen's The Orbriallis Institute: Lost Grove, Part Two was a fascinating and intricate read. It moved quickly with all the turns and twists, and I never knew what would come next. I was in suspense and kept on the edge of my seat during this page-turner. I was too scared to put the book down for even a minute for fear of missing something. The characters were authentic and relatable. Only her friends listened to Nettie when she insisted that the Green Man was to blame for her brother's disappearance and made an effort to learn the truth. This well-written story includes murder, betrayal, mystery, and obsession, and a number of the subplots come together seamlessly. The ending was superb, and it exceeded my expectations by far.
