Double Eclipse — Melissa de la Cruz

Twin witches Mardi and Molly Overbrook are back for another summer in North Hampton, and this year they're serious about two things: avoiding trouble and dedicating themselves to rest and relaxation. Molly's headed to Aunt Ingrid's, while Mardi has convinced their father, Troy -- a.k.a. Thor, the god of thunder -- to let her crash with her boyfriend, Trent, who also happens to be Tyr, the god of war. It's a tangled web they weave, but that's to be expected where gods and goddesses are concerned.

Their vacation's just begun when an old secret is revealed, leaving Molly and Mardi to question everything they've ever known about their family. Then a hot new guy comes to town and starts brewing even more trouble . . . and soon enough, the twins are back to their old tricks.

After an ancient prophecy comes to light, Molly and Mardi notice some mysterious changes, changes that will put their sisterhood to the ultimate test. East End's shaping up to be much more exciting than the girls were bargaining for, but what's a summer in the Hamptons without a little magic and mischief?
