Ten-year-old Aldo isn't athletic like his older brother and he's not a rock hound like his best friend, but when his grandmother gives him a sketchbook to record all his "artsy-fartsy ideas," he discovers that he's a pretty good cartoonist. In this new installment of Aldo's adventures, Aldo finds himself thinking he's Einstein. Gloating over his exemplary first-quarter grades and test scores, he even decides to dress as the iconic scientist for Halloween. His bubble is burst, though, when he realizes that he's not excelling in one class, EspaĆ±ol, and that the consequences may be more hurtful than a bad grade on a report card.Is Aldo's friendship with his bilingual best friend, Jack, at stake? As always, this addition to the A-to-Z alphabet series features a vocabulary-building glossary of fun and challenging words starting with the letter E, such as erudite, eureka, epiphany, and éclair.
