Piper Hayes was weeks away from college graduation when two missing scientists left her with their toddler—and a trail of danger that led straight into a world of gangs, corrupt agents, and a seductive threat in a CIA badge.

All Piper wanted was to return the child to safety. Instead, she ends up on the run with Sebastian Rivera, a grad student with a past in D.C.'s gang underworld and a dangerous sense of protectiveness she doesn't know if she can trust. As Piper digs deeper into the disappearance of her best friend and the mystery surrounding a sabotaged pharmaceutical project, she uncovers a twisted conspiracy that stretches from back-alley dealers to Capitol Hill.

Caught between two cousins—one fighting for her safety, the other willing to trade it—Piper must decide who deserves her trust before she loses everything. But when the man tasked with protecting the country turns his obsession on her, Piper realizes the most dangerous thing in her life isn't the gangs outside the house.

It's the man already inside.
