Perfect for you if...

You love Scarpetta's forensic brilliance and want a case that blurs the line between the supernatural and the sinister.
You're drawn to high-concept crime thrillers where the victim becomes a puzzle that only one person can solve.
You're curious about how Cornwell adapts her 30-year-old character to contemporary mysteries involving UFOs and impossible crime scenes.

Maybe not for you if...

You prefer standalone thrillers over long-running series, as this is book 34 in the Scarpetta saga.
You want gruesome autopsy details to dominate the plot rather than personal entanglement with the victim.
You're sceptical of supernatural elements in crime fiction and won't enjoy the UFO angle even as misdirection.

About this book

Dr. Kay Scarpetta is called to an abandoned theme park to retrieve a body and discovers the victim is a man with whom she once had an intense romantic relationship. The murder scene is unusual, featuring a crop circle of petals around the body and the victim's strangely red skin. Scarpetta's niece Lucy theorizes the body was dropped from an unidentified flying craft. Scarpetta performs an autopsy to uncover the victim's secrets and is surprised to find evidence suggesting her friend deliberately left her a clue. As investigators debate whether otherworldly forces or the victim himself are responsible, Scarpetta identifies an explanation rooted in more earthly—and sinister—circumstances.
