The lifeboat clique / Kathy Parks.

Some people might say that Denver has a death wish. Why else would she dare to sneak into a Malibu beach party where she'd be surrounded by enemies, including her ex-BFF, Abigail? Oh yeah. Croix. Denver never thought in a million years he'd ask her out, but who is she to question this miracle of fate? Well, that isn't the only surprise fate has in store. During the party a tsunami hits the coast of California, wiping out everything in its path. Denver and a handful of others escape death and are swept out to sea. Of course, one of her fellow castaways is none other than Abigail, who can barely stand the sight of her. Now that she's floating on the ocean, stuck on a small boat with the most popular kids in school and waiting to be rescued, Denver wonders what might kill her first - dehydration, sunstroke, or the girl she used to think of as a sister.
