Cheer the Eff Up - Jonas' unorthodox letter to his unborn child - holds so much in an entirely unassuming package. It's a time capsule that includes reflections on family, youthful ambitions, aging in punk, work, gender identity and fatherhood, and the way things change. It's humorous, heavy, and profound - often in the same sentence. Highly recommended. 56 pages, half-letter size.
