When Katie Weber was 23, she was diagnosed with a rare brain tumor. After surgery and treatment, she seemed good to go—until a relapse at 28 sent her life into a spin and forced her to forge a new identity and give up many of her dreams.

This is a cancer memoir, because it’s about and written by a young woman who gets cancer, but it’s so much more than that. In many ways, cancer causes us to ask all of the same questions about life any of us ask, but at a much faster rate. Questions about meaning and existence that just don’t seem to have clear answers. Katie especially lives in the gray right now, but really, we all do.

In Living in the Gray, by Katie Weber, we learn that the gray is something we all need to be comfortable with, because uncertainty is the only thing we can ever be certain of.
