Sarah receives a package in the mail from her recently deceased grandfather: a life-size robotic version of him! Sarah enjoys spending time with robo-grandpa, but her mom thinks the invention is creepy. One night while Sarah sleeps, her mom sends the robot to the scrap heap leaving only one hand behind. Sarah holds on to it as a memento of her beloved grandfather but like Sarah, the hand has problems letting go. This series of Hi-Lo books is sure to grasp any reluctant reader and refuse to let go until the final page. Each book includes discussion and writing questions, a glossary, and educational back matter.
