Family secrets and fresh romance collide in this heart-pounding Richter series installment by New York Times and USA Today bestselling author Catherine Bybee.

Jacqueline "Jax" Simon knows how to expose secrets: she's a skilled operative with MacBain Security and Solutions. When Jax hears her parents are divorcing, she races to London to find out why. She's determined to learn the truth, especially when her investigation uncovers why her parents sent her to Richter, the German military school that made her a fighter.

Andrew Craig collects Jax at Heathrow Airport as a favor. He's heard she's a handful, but he didn't know she's dangerously gorgeous too. His instant attraction could change his life...or end it.

Jax doesn't want to fall for Andrew, but soon he's worming his way into her life. Together, they infiltrate Richter to discover if it has returned to its covert purpose: training children to be spies and assassins and blackmailing parents to look the other way. As the attraction between the two intensifies, so do the secrets exploding all around them. How deadly are those secrets--and who will survive?
