Sienna Nealon

The first edge-of-your-seat novel from the million-selling Girl in the Box series by Robert J. Crane.

Locked away in her own home for 12 years by a mother hiding dark secrets, 17-year-old Sienna Nealon has never known the outside world. That changes when she wakes to two intruders in her house, forcing her to break every rule she's lived by. Trained in brutal self-defense and sensing a strange power stirring inside her, Sienna fights back with raw fury, smashing through the door into a blinding, frozen reality she's only glimpsed from behind barred windows. But freedom comes at a cost: bullets, betrayal, and a truth that could unravel everything.

Now on the run from a shadowy government agency and a killer obsessed with her emerging abilities, Sienna wrestles isolation, sarcasm, and a hunger she can't control. In this fast-paced urban fantasy thriller, ancient myths collide with modern nightmares in a world of superhumans.

Listeners call it "a thrill ride with a kick-butt heroine" and praise the "mix of mystery, romance, and edge-of-your-seat action that hooks you like The Hunger Games." If you love Jim Butcher's snarky grit or X-Men-style powers, this million-copy series starter will keep you up listening all night.
