The Howling Timberwolves series of Orca Echoes early chapter books offer lots of sports action and humour that will appeal to young boys. Johnny Maverick and his friends play for the Timberwolves peewee hockey team in the small town of Howling. Tom Morgan has just moved from Toronto and is a talented player. Tom is also very competitive and seems determined to pick on Stu Duncan, who is slightly overweight. Johnny suggests a race between Tom and Stu. Tom eagerly accepts; Stu is reluctant but Johnny convinces him to trust his best friend's advice. On race day Tom is surprised by both the race and its outcome and learns that teamwork pays off. Also available in French.
This book is fantastic! A school where kids don't fight and don't bully, and get the best of new-kid-bullies by using their wits. An overweight kid an his athlete friend who let insults (to the overweight kid) roll off their back by channeling Oprah. Peace and friendship for everyone in the end. What's not to love? I kind of want to read it aloud to my class, though it's way below their reading level.
