In the tradition of The Fault in Our Stars, critically acclaimed author Melissa Kantor masterfully captures the joy of friendship, the agony of loss, and the unique experience of being a teenager in this poignant new novel about a girl grappling with her best friend's life-threatening illness.

A person's whole life, she's lucky to have one or two real friends. Friends who are like family For Zoe, that someone is Olivia. So when Olivia is diagnosed with leukemia, Zoe is determined to put on a brave face and be positive for her best friend.

Even when she isn't sure what to say. Even when Olivia misses months of school. Even when Zoe starts falling for Calvin, Olivia's crush.

The one thing that keeps Zoe moving forward is knowing that Olivia will beat this, and everything will go back to the way it was before. It has to. Because the alternative is too terrifying for her to even imagine.
