Sixteen-year-old Mel wishes she and her little sister could be close again, but when Annie spills that she’s knocked up, Mel loses any hope of that happening. There’s just no way Mel’s life full of girl friends and cooking can compare with Annie’s world full of boyfriends and sex. Still, Mel promises she’ll keep Annie’s secret, figuring it’s the only way to save their remaining bond.

Enter Devon, the first guy ever to make Mel feel like the special sister. But the closer she and Devon get the more Mel has to pepper their relationship with little lies to hide her sister’s pregnancy. When Annie drops another bomb, Mel’s afraid she’ll lose Devon if she keeps the secret, or lose her sister for good if she doesn’t. Her only other choice is to stay true to herself, something she hopes she can remember how to do on her own.
