A wordless graphic novel provides a plangent meditation on the nature of friendship. When a dog buys a mail-order robot kit and puts it together, the two become fast friends. On an ill-fated trip to the beach salt water works its corrosive way on the robot, and the dog is forced to leave his immobilized friend lying on its towel on the sand. Their separate stories unfold over the next 11 months, as the dog makes an effort to repair his friend, only to discover the beach has closed, then turns to other friendships, while the robot lies suffering the ravages of weather and neglect and dreaming of friendships past and possible. Varon’s muted blues, grays and browns set the emotional tone for this tale, angularly regular hand-framed panels that only rarely vary with frameless images serving to emphasize the emotional confinement of her protagonists. The resolution is psychologically ambiguous, denying readers the satisfaction of a happy reunion but offering them the harder-edged truth that friendships change and die—but others can rise in their place. Witty and plaintive by turns, this is thoughtful, provocative pleasure. (Graphic novel. 8-14)
