Insomnia

Emma Averell has built the life she always wanted: a demanding career as a divorce lawyer, two children she adores, and a devoted stay-at-home husband. It is a world away from the childhood she never talks about, the one that landed her and her older sister in foster care after something terrible happened with their mother.

Emma's fortieth birthday is twelve days away, and she can't sleep. Her mother stopped sleeping too, right before she turned forty, right before she changed into someone unrecognizable. As the sleepless nights pile up and the hours blur together, Emma starts losing time, misplacing memories, and doubting what she sees. She is terrified that whatever unraveled her mother is written into her own blood, and that her family may not be safe from her.

A tense, claustrophobic thriller from the bestselling author of Behind Her Eyes, Insomnia burrows into the fear that we might become the very people we swore we never would.
