Twenty-Seven Bones

The brilliant author of Fear Itself pulls readers into an intricate web of ritual killings orchestrated by an evil pair of murderers who always manage to be one step ahead of the law.
Former FBI Special Agent E.L. Pender may be retired, but he jumps at the chance to help solve a particularly gruesome series of crimes in the U.S. Virgin Islands.
This is no ordinary case, seeing as the right hand on each body in the string of murders is missing. The police want to keep the existence of a serial killer under wraps; they hope to solve the crime before a stampede sets in. Meanwhile, Pender is convinced the killer must be the husband of the last victim and sets out to capture him -- but he's only partly right. The husband is connected to the case, but the real murderers are a cunning husband-and-wife team of archeologists who believe that if they breathe in their victim's last breath they will live forever.
Never before has Pender come up against such savvy, diabolical opponents. From one trail of dead ends to another, readers will feel Pender's fever to prevent more murders from occurring...and his sheer panic when he can't. Twenty-Seven Bones is that most quintessential of thrilling reads, providing a visceral experience of chills and excitement on every page.
