Tru has been hiding all her life. Her parents taught her to conceal her bastion Talent: indestructible skin, muscles, and bones. In a world where Talents are common and varied, no one trusts a bastion--they're too powerful. Hiding failed to keep Tru's parents alive, but moments before their murder, Tru's mom pointed her to Logan Dire, a famed recluse assassin who adopted and trained orphaned Tru. At seventeen, she's still hiding. Not even her closest friends know her true name or Talent, or that she's balancing high school with knife and stealth training (while crushing on her BFF's older sister). When assassins interrupt a mundane babysitting job booked through BountyApp--where lethal hunters find work and babysitters for their kids--Tru flees with a one-year-old strapped to her chest and spiraling questions: Who killed her parents? Whom can she trust? What does it mean to be a bastion? And is it ever OK to kiss a girl who's trying to hunt you down?
