Twelve cold cases. Twelve kidnapped women. One diabolical serial killer. In this riveting suspense thriller, a brilliant FBI agent faces a deadly challenge: decipher the mystery before each one is murdered.

In the Maya Gray series (which begins with Girl One: Murder), FBI Special Agent Maya Gray, 39, has seen it all. She’s one of BAU’s rising stars and the go-to agent for hard-to-crack serial cases. When she receives a handwritten postcard promising to release 12 kidnapped women if she will solve 12 cold cases, she assumes it’s a hoax.

Until the note mentions that, among the captives, is her missing sister.

Maya, shaken, is forced to take it seriously. The cases she’s up against are some of the most difficult the FBI has ever seen. But the terms of his game are simple: If Maya solves a case, he will release one of the girls.

And if she fails, he will end a life.

In Girl Nine: Gone (book nine), Maya realizes that time is running out fast when she discovers new victims of a serial killer left, at each crime scene, with an antique moon dial beside them. This killer must be counting down according to the moon’s light.

Yet in a shocking twist, nothing is what it seems.

And Maya realizes too late that she herself may just be the target.

A complex psychological crime thriller full of twists and turns and packed with heart-pounding suspense, the Maya Gray mystery series will make you fall in love with a brilliant new female protagonist and keep you listening late into the night. It is a perfect addition for fans of Robert Dugoni, Rachel Caine, Melinda Leigh, or Mary Burton.
