This Island Isn't Big Enough for the Four of Us! — Gery Greer

Pete and I stared at each other. Two girls camping on our island?

Pete and Scott are horrified when they find Sunny and Jill camping with Jill's aunt on Turtle Island, the same "deserted" wilderness where Pete and Scott planned to have a few death-defying adventures. Alone. Every time the boys mess up, Sonny and Jill are there, taking the picture. This is war -- boys against girls!

With the help of an eccentric recluse who lives on the island, the boys plan one final battle -- a wacky contest of wit, skill, and revenge -- to determine the champions of Turtle Island!
