Some friendships are easy, and some are more complex.Sixth graders Gabe and Oliver have been best friends since pre-K, when sporty Oliver inspired bookish Gabe to try the teeter-totter-and encouraged him to keep trying it until he got the hang of things. This became the basis of their philosophy of complementary friendship. It's a solid relationship but one that Gabe sometimes worries about as their interests diverge. However, they're still a natural choice to work together when their teacher gives the class a storytelling assignment that can take any format they wish. The duo embarks on creating a comic that chronicles the adventures of Gabiver, a fictional detective and crime fighter inspired by Dav Pilkey's Dog Man who is a composite of the two boys. Their assignment-and their friendship-is changed with the addition of new student Reuben, a boy who doesn't talk, and seventh grader Rae, a girl who refuses to atone to a teacher for voicing her opinion and must spend time with the younger class until she crafts an apology. The story does a lot of things well, including its subtle examination of masculinity and friendship, although it suffers slightly under some far-fetched plot points, excessively tidy resolutions, and easy summations of trauma. Readers looking for a breezy read will most likely be pleased, but those hoping to sink their teeth into something meatier may find it too saccharine. All main characters read White.Sweet but superficial. (Fiction. 8-12)
