In the final book of this hit summer reading series for ages 8 to 12, this summer is definitely not average. This three-book series is great for sports fans and reluctant readers, with Camp Average shortlisted for provincial children's choice awards in Manitoba, Ontario, and Saskatchewan.

It’s another summer at Camp Avalon—also known as Camp Average to its campers—only this year, things are anything but normal. Mack and Andre are spending the summer at rival Camp Killington, where the competitive campers seem intent on making them suffer.

Meanwhile, at Camp Average, Miles is trying to keep the peace—which is not easy, due to obnoxious newcomer Garth and his pranks. On top of that, Miles has another impossible task on his plate: getting Mack and Andre back on home turf.

Things come to a head when Mack and Andre are forced apart, and Cassie challenges Garth to a do-or-die ball hockey showdown. Will the Camp Average crew find their way back together and come out on top? In this third and final addition to the critically acclaimed Camp Average series, the campers rally to support each other and discover once more how teamwork and cooperation win.
