(3) K-3 Ready-to-Read: The Adventures of Otto series. "See Otto feel sad. // No... Wait..." Twice, robot Otto gets his hopes up when he sees a friend approaching (offering a hug, then a pie). Twice, he's disappointed that he's not the intended recipient. Then Pip appears with a kite, and Otto prepares himself for rejection. Surprise! Pip wants to play with Otto! In this ninth entry in the series (Swing, Otto, Swing!, etc.), the spare, easy-to-decode text and cheery uncluttered illustrations satisfyingly convey Otto's emotional lows and eventual high.

(2) K-3 Ready-to-Read: The Adventures of Otto series. After watching bird Tweet fly, mouse Pip becomes inspired to try it. Several page-turns (and much fruitless flapping) later, robot friend Otto comes up with a clever remote-control drone solution that allows Pip's dreams to take flight. This latest series entry's extremely limited vocabulary provides effective new-reader support, the comic timing is spot-on in the repetition and pacing, and the clean illustrations are both understated and hilarious.

(2) K-3 Ready-to-Read: The Adventures of Otto series. The simplest of easy-reader texts ("Give, Santa, give"), accompanied by action-packed illustrations, relates Otto the space robot's latest adventure. The animals so love their new presents (drum, squirt gun, football) that Santa, lounging on the beach, can't get any rest. But dependable Otto comes to the rescue, and, soon enough, we "see Santa nap." Ho, ho, ho. See readers laugh.
