There are two sides to every love story. Even supernatural ones. This is the companion novel to David Levithan’s unforgettable bestseller Every Day.

Every day is the same for Rhiannon. She has convinced herself that she deserves her distant, moody boyfriend, Justin. She knows the rules: Don’t be needy. Avoid upsetting him. Never get your hopes up.

Then, out of the blue, they share a perfect day together - perfect, that is, until Justin doesn’t remember anything about it. Confused, and yearning for another day as great as that one, Rhiannon starts to question everything. And that’s when a stranger tells her that the Justin she spent that time with & wasn’t Justin at all.

Levithan’s powerful novel explores the complexities of first love in a unique way that will captivate anybody who loved Rainbow Rowell’s Eleanor & Park and Jandy Nelson’s I’ll Give You the Sun.
