Heart Failure by Chris Zett

An enemies-to-lovers lesbian romance about daring to open your heart.

Dr. Jess Riley’s life is perfect, ticking all the boxes—successful cardiologist, newborn daughter, and a luxurious condo. That is, until she suddenly collapses from acute heart failure. Her entire world crumples along with her exhausted body.
Jess is forced to face facts—she can’t keep working endless hours, and she’ll have to move back home to recover.
To her shock, her mother has already taken in Lena Walker, a struggling artist who isn’t a stranger to heartbreak either.
At first, an unimpressed Jess resents Lena’s cheerful presence. Gradually, though, the two women form a tentative friendship over tai chi, picking fruit, and evening walks with the baby. A sexy massage leads to friends-with-benefits fun. But is it all too soon? Should two barely mended souls try to risk a future together?
