What if the person you trust the most did something you can't forgive?

Dana Blair has spent her life letting others take the wheel, from her relationship with her husband to her business. Now, with her marriage unraveling, her son in crisis and her career on the verge of collapse, Dana is left wondering whether she ever really had control of anything at all.

Padma Paulsen is the opposite: a brilliant, fiercely driven ER doctor who's given her all to her career. Her friendship with Dana has been the one constant in her high-pressure life.

But then a tragedy on Padma's watch leaves Dana's daughter in critical condition and their bond in tatters.

As Dana fights for justice for her daughter, grief turns to blame. Soon she's forced to make a decision that could either save her family or destroy the most important friendship of her life.

Who We Used to Be is a powerful story about the ties that hold us together, the pain that can pull us apart, and the courage it takes to find your way back--to yourself and the people who matter most. Perfect for fans of Sally Hepworth, Laura Dave and Liane Moriarty.
