my seventh book

I'm reading a book called This Island Isn't Big Enough For The Four Of Us! long title huh? well this story is about two boys Pete and Scott they go to and Island to challenge nature but two girls that were already on the Island are just waiting to take away their fun. As Scott and Pete were arriving on their canoes a flash of light enters their eyes they see to girls giggling in the bushes one of them has a camera her name is Jill and the other one is Sunny. That single snap shot made every thing crazy, each side trying to get revenge on each other but it was Scott and Pete that started the hole revenge thing. Through out the hole story each side were playing traps and tricks on each other until Cornelius and Katherine get involved. Katherine is Jill's aunt and Cornelius is a person that Scott and Pete found in the Island. Those two have met before and Cornelius kind of likes Katherine.they come up with an idea a race to see who are the champions of Turtle Island.
