Right before winter break, fourteen-year-old Molly Rosenberg reluctantly volunteers to participate in Santa Monica's annual homeless count, just to get her school's community service requirement out of the way. But when she ends up meeting Red, a spirited homeless girl only a few years older than she is, Molly makes it her mission to reunite her with her family in time for Christmas. This turns out to be extremely difficult--because Red refuses to talk about her past. There are things Molly won't talk about either. Like the awful thing that happened last winter. She may never be ready to talk about that. Not to Red, or to Cristo, the soulful boy she meets while riding the Ferris wheel one afternoon. When Molly realizes that the friends who Red keeps mentioning are nothing more than voices inside Red's head, she becomes even more concerned about her well-being. How will Molly keep her safe until she can figure out a way to get Red home?
