Love, Lattes and Angel

Some teens go to the Caribbean on spring break. Piper goes to save the world.
Piper Dunn isn't who you would call a normal teenager. For one thing, she doesn't want anyone to know she was born with a blowhole. Even stranger, she has two love interests. Joel, a fellow dolphin-human hybrid, and Tyler, a human.
It's hard to choose when a mad scientist is hot on Piper's trail. Worse, she's trapped in the Bermuda Triangle. And . . . wait for it . . . Angel, her test-tube daughter, is apparently a real-deal reincarnation. It all adds up to an impossible situation, with happy endings all but lost at sea. Unless, of course, a voodoo high priestess casts a spell or two . . .
