Who would have thought the notoriously spooky little town of Nightshade,
California, could get twice as weird? The summer before Daisy Giordano's
senior year, it does. With their mom working on a case overseas, the
Giordano sisters are on their own. These smart psychic teens have no
trouble taking care of themselves. They score jobs: Daisy starts working
at her favorite diner, Slim's; beach-loving Poppy mans a snack stand on
the boardwalk; and Rose lands a coveted position as a research assistant
to the mysterious Dr. Franken. But then summer gets strange. Residents
of Nightshade are suddenly seeing double. Doppelgangers -- look-alikes
of familiar friends and neighbors -- are popping up all over town.
Daisy, Rose, and Poppy think it's a coincidence, until the rumors start
that their father, who disappeared several years ago, is back in
Nightshade. Perhaps the girls won't be having a parent-free summer after
all. Meanwhile, Daisy's boyfriend, Ryan, is spending all of his time
training for football, and like the other guys on the team, he's grown
enormous almost overnight. Could the players be resorting to extreme
measures to win? Between psychic predictions, sugar rushes, and beach
parties, the Giordano sisters get to the bottom of these mysteries and
more.
