Macy Hollinquest is eleven years old, and don't count on her to change that anytime soon. Her birthday is just days away, but she has no intention of turning twelve without her dad by her side. He'd promised to be there for her big day, and yet he's been gone for months -- away after his discharge from the army, doing some kind of top secret, "important work." So Macy's staying eleven, no matter what -- that is, until she meets Ginger, a nice older lady who is searching for her missing dog. Ginger's dog search is the perfect cover for Macy's attempt to locate her dad. But her hunt puts her on a path to a head-on collision with the truth, where she discovers that knowing can sometimes be a heavy burden. And that change, when finally accepted, comes with an unexpected kind of grace.
