12 cold cases. 12 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 Book 1—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 Seven: Craved, women are turning up dead with a precious stone mysteriously left on their bodies. What type of stone is it? What is the significance?

Will it lead to the Moonlight Killer?

And who will he target next?

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.

Books 8 and 9 in the series—Girl Eight: Hunted and Girl Nine: Gone—are now also available.
