Security specialist and PI Jamie Sinclair crosses interstate boundaries—and personal ones too—in this electrifying thriller from an award-winning author who “understands how to keep her readers riveted from beginning to end” (USA Today).

With a long list of high-profile, high-paying clients, Jamie Sinclair has her hands full—and that’s the way she likes it. Still reeling from the brutal investigation that drove a wedge between her and her boyfriend, military police officer Adam Barrett, Jamie is counting on hard work to help her forget her recent history—but then DEA agent Marc Sandoval barges back into her life. The last time they worked together, Jamie almost crossed all kinds of lines. Now Marc doesn’t just want Jamie, he needs her . . . because she’s the only one who can help him—and the little boy he never told her about.

Marc’s ex has vanished, leaving their six-year-old son in his care. Despite a troubled past, Elena never wavered in her duties as a parent, so something must be very wrong now. Teaming with Marc to track Elena through her home state of Colorado and beyond, Jamie finds herself on a cross-country search for the missing mother of Marc’s child, at a crossroads with Adam, and on a collision course with the killers who’ll stop at nothing to find Elena first.
