Reviews

I just finished Transplant by Deborah Siminou and was deeply moved by how the novel intertwines a personal journey with the dark realities of a drug and more cartel. Siminou vividly shows how the cartel's influence spreads fear and unheaval, forcing characters into touch decision and revealing the heavy consequences of involvement--whether by choice or circumstance. The story doesn't offer easy answers, instead highlighting the complexity and humanity of those caught in the cartel's shadow. Overall, Transplant is a gripping, though-provoking read about survival and the far-reaching impact of organized crime. Lots of twist and turns . This one will keep you turning the page until too late at night. Well written with memorable characters, some you love and some you love to hate. Highly recommend. TRANSPLANT is a fast-paced, high-adrenaline medical thriller. It moves like an ambulance with no brakes-straight into the next crisis. In her debut novel, Deborah Siminou plunges the reader into the frightening world of illegal, deadly surgeries against a backdrop of international intrigue. Ruby, an accountant with personal troubles, is a likable underdog heroine. The story reminded me of the tradition of Robin Cook, Michael Palmer, and Tess Gerritsen.
