When eleven-year-old Hank's mom doesn't come home, he takes care of his toddler sister, Boo, like he always does. But it's been a week now. They are out of food and mom has never stayed away this long... Hank knows he needs help, so he and Boo seek out the stranger listed as their emergency contact.

But asking for help has consequences. It means social workers, and a new school, and having to answer questions about his mom that he's been trying to keep secret. And if they can't find his mom soon, Hank and Boo may end up in different foster homes--he could lose everything.

Gennifer Choldenko has written a heart-wrenching, healing, and ultimately hopeful story about how complicated family can be. About how you can love someone, even when you can't rely on them. And about the transformative power of second chances.
