Author Biography

Karen Gilleland is the author of the Diamond-Dennison mystery series. She resides in Boulder, Colo., at the foot of the Rockies, but as a Pisces, she loves the ocean and cruises whenever possible, trips which spawned her second mystery, Diamond on the High Seas.

She spent most of her career as a corporate writer, but after becoming an insanely addicted fan of the Britcom “Doc Martin,” she began writing FanFiction and posted 28 stories on her blog, which reached more than 660,000 visitors. She even traveled to Cornwall to appear as an extra in “Doc Martin,” Series 7, Episode 3.

Writing fiction was so enjoyable that, homebound during the pandemic, Karen branched out into mysteries. The fun continues, as she’s now working on her third book in the Diamond-Dennison series.

Reviewed by Pikasho Deka for Readers' Favorite

Diamond on the High Seas by Karen Gilleland is about Hope Diamond, a tenacious woman who heads Diamond Security, one of the elite firms providing protective services to high-risk individuals. She is hired for a job by her cousin Ruth Austin, whose husband Leonard's life is in danger due to his work as an accountant for the military technology company, MOS. Hope finds herself aboard the Iris of the Seas cruise ship, where she runs into her former lover, Matt Dennison, an FBI agent tasked with capturing a traitor and preventing vital microfilm from falling into the wrong hands. However, two successive murders on the ship during a storm at sea will force Hope and Matt to put their feelings aside and work toward capturing the killer before more lives are lost.

Diamond on the High Seas is a captivating whodunnit set on a cruise ship full of suspects. What more can a murder-mystery fan ask for? Karen Gilleland's gripping story is full of action, suspense, intrigue, and romance, and you will be hard-pressed to find a dull moment. The two lead characters, Hope and Matt, exude infectious chemistry, and their relationship forms the anchor around which the plot revolves. The sheer number of characters makes it difficult for readers to identify the killer, and you will find yourself looking for clues until the final revelation. I thoroughly enjoyed Diamond on the High Seas and recommend it to murder mystery lovers.
