Death eventually comes for us all. But what if there's a way for older people to regain their youth? To stay a step ahead of the grim reaper? Turning 40 was the last straw for me. It's practically 60 in gay years and I wasn't ready for dentures yet, so I came to Youthology -- a program that injects clients with blood transfusions from young, fit and healthy donors. I chose Nick. Handsome. Masculine. And more importantly, young. I thought I hit the lottery, until my life started to change for the worst. Not even the top medical experts can explain what happened to me. From the moment Nick's blood flooded into my veins, I stopped being me, and I became something new; something dangerous and deadly. I became my donor. His obsessions are mine now. His darkest desires, his dreams, his needs, and nightmares are all a part of me, and I don't want to let them go. I embrace them and the beautiful boy who haunts both of our dreams. My blood pact was sealed the moment I entered Youthology. I never thought I'd become a killer. This book is part of CRIMINAL DELIGHTS. Each novel can be read as a standalone and contains a dark M/M romance. Warning: These books are for adult readers who enjoy stories where lines between right and wrong get blurry. High heat, twisted and tantalizing, these are not for the fainthearted.
