Tallie’s life sometimes feels like one long missed connection. She never knew her mom, who died the day Tallie was born. And seven months ago, Tallie spent five magical hours with Thomas, a boy who felt like her soulmate, only for them to get separated. Life spins on, but she knows there’s an unfinished love story out there, waiting for her.

Now Tallie’s facing something even bigger: the same heart condition that killed her mom. In forty-nine days, she’ll have the surgery that could save her—or end her story forever. Determined to live before she dies, Tallie decides to track down Thomas. She finds his phone number and sends a text . . . but the wrong boy replies.
