کتاب The Third Twin ( رمان سومین دوقلو)

IT STARTED AS A JOKE.
When they were little, Lexi and her identical twin, Ava, made up a third sister, Alicia. If something broke? Alicia did it. Alicia was always to blame for everything.

NOW THE GAME IS ALL GROWN UP.
The girls are seniors, and they use Alicia as their cover to go out with guys who they’d never, ever be with in real life. But sometimes games just aren’t worth playing. A boy has turned up dead, and DNA evidence and surveillance photos point to only one suspect—Alicia. The girl who doesn’t exist.

IDENTICAL TWINS. IDENTICAL DNA. IDENTICAL SUSPECTS.
Ava insists that if they keep following the rules for being Alicia, everything will be fine. But Lexi isn’t so sure. She must find the truth before another boy is murdered.

BECAUSE EITHER AVA IS A KILLER . . . OR ALICIA IS REAL.
