King puts a unique and sexy spin on Dr. Jekyll and Mr. Hyde. The plot is well crafted, the science well written and the characters well developed. Sex plays a prominent role, but there's also plenty of emotion. Even if you haven't read the previous installments, book four of the Sterling Files series can be enjoyed as a stand-alone. It's a satisfying ending that leaves things open for a sequel.
Dr. Henri edouard has created a drug designed to produce invincible soldiers. He injects himself, becoming a test subject for a serum that changes him almost beyond recognition. A danger to others, he goes on the run, and the Sterling Research Centre sends Dr. Alison Cunningham after him. But the government wants him too. Alison must evade the military and keep Henri safe if she's to bring him in, though her feelings for Henri put her own life in jeopardy. (ELLORASCAVE.COM, dl $5.95)
