This is what it means to love someone. It's a little bit like infinity.

Gottie H. Oppenheimer is...seventeen. Motherless. A math genius. And she's losing time. Literally.

When the fabric of the universe surrounding Gottie's sleepy seaside town begins to fray, she is hurtled through wormholes to her past:

To last summer, when her grandfather Grey died.

To the afternoon she fell in love with Jason, who wouldn't even hold her hand at the funeral.

To the day her childhood best friend Thomas moved to Canada, leaving her behind with a scar on her hand and a black hole in her memory.

Although Grey is still gone, this summer Jason and Thomas are back, and Gottie's past, present, and future are about to collide -- and be changed forever.

With time travel, quantum physics, and world-stopping kisses, this stunning YA debut is an exponentially enthralling story about love, loss, and figuring it all out.
