Carly and her little sister Jen are walking. Something terrible has happened. Something that has left Carly in charge, her faith in humanity shattered. She knows they need help. But she is terrified of her sister being taken away from her. All they have is each other.
Carly wants them to find their way back to the last person she knew she could trust – their stepfather. But Jen holds a secret about him which, if she’s telling the truth, will put them both at far more risk than they could imagine.
And so begins a journey, across hundreds of miles, which neither girl could have anticipated. It isn’t an easy one, and is often dangerous. But along the way they are also confronted with the unexpected kindness of strangers. And ultimately, should they choose to accept it, some new relationships that hold the potential to change everything.
