LOVE TIMES TWO;

I just barely started reading the book and so far it's about two sisters that go on vacation and end up falling for the same boy apparently. I read the back of the book and it says that Claudia and Cassie, the two sisters, vacation with their family at Green Lake and start liking the same boy, TJ. It also says that the sisters have always been as close as sisters can be. However, will their so-called love for TJ distance them from one another if one of them wins TJ's love?
