Bounce House is a collection of small containers for the uncontainable. Restrained in form but not feeling, Harper’s fourth book explores the cyclical nature of grief, imperfect parenting, and our willingness to jump without promise of a safe landing. Measured and meticulously weighted, these poems are playful and poignant as they navigate the strange terrain around losing a loved one: how the past and present blur together, the dead simultaneously here and missing, and how joy moves inevitably forward, as if on wheels.
