Family has always been important to twelve-year-old Maggie: a trapshooter, she is coached by her dad and cheered on by her mom. But her grandmother's recent death leaves a giant hole in Maggie's life, one which she begins to fill with an assortment of things: candy wrappers, pieces of tassel from Nana's favorite scarf, milk cartons, sticks . . . all stuffed in cardboard boxes under her bed.

Then her parents decide to take in a foster infant. But anxiety over the new baby's departure only worsens Maggie's hoarding, and soon she finds herself taking and taking until she spirals out of control. Ultimately, with some help from family, friends, and experts, Maggie learns that sometimes love means letting go.
