Karina Ahmed has a plan. Keep her head down, get through high school without a fuss, and follow her parents' rules--even if it means sacrificing her dreams. When her parents go abroad to Bangladesh for four weeks, Karina expects some peace and quiet. Instead, one simple lie unravels everything.

Karina is my girlfriend.

Tutoring the school's resident bad boy was already crossing a line. Pretending to date him? Out of the question. But Ace Clyde does everything right--he brings her coffee in the mornings, impresses her friends without trying, and even promises to buy her a dozen books (a week) if she goes along with his fake-dating facade. Though Karina agrees, she can't help but start counting down the days until her parents come back.

T-minus twenty-eight days until everything returns to normal--but what if Karina no longer wants it to?
