National Book Award-winning and New York Times bestselling author Robin Benway returns with a story of love, loss, and sisterhood reminiscent of I'll Give You the Sun and Every Day. Told in reverse chronological order, A Year to the Day will claim a permanent home in your heart.

IT'S BEEN A YEAR-A YEAR OF MISSING NINA

Leo can't remember what happened the night of the accident. All she knows is that she left the party with her older sister, Nina, and Nina's boyfriend, East. And now Nina is dead, killed by a drunk driver and leaving Leo with a hole inside her that's impossible to fill.

East, who loved Nina almost as much as Leo did, is the person who seems to most understand how she feels, and the two form a friendship based on their shared grief. But as she struggles to remember what happened, Leo discovers that East remembers every detail of the accident-and he won't tell her anything about it. In fact, he refuses to talk about that night at all.

As the days tumble one into the next, Leo's story comes together while her world falls apart. How can she move on if she never knows what really happened that night? And is happiness even possible in a world without Nina?
