Mercy on These Teenage Chimps

On his thirteenth birthday, Ronnie woke up feeling like a chimp--all long armed, big eared, and gangly. He's been muddling through each gawky day since. Now his best friend, Joey, has turned thirteen, too--and after Joey humiliates himself in front of a cute girl, he climbs a tree and refuses to come down. So Ronnie sets out to woo the girl on Joey's behalf. After all, teenage chimps have to stick together.
    

Acclaimed author Gary Soto tells a fun and touching story about friendship, understanding, and the painful insecurities of being thirteen.
