In their final month of elementary school, 11-year-old Aldo Zelnick and friends are faced with a series of Lasts: Last Cafeteria Meatloaf; Last Band Concert; Last Monkey Bars Fail. Blindsided by an uncharacteristic sense of loss, Aldo decides to bag some new Firsts--including putting himself out there for the 5th grade talent show--only to be beset by a series of logjams. This twelfth installment in an A-to-Z alphabet series also includes a glossary of fun and challenging "L" words, such as lackadaisical, loony, and limbo.
