The Other One

Anna has always known that she has a sister.
Cleo is everything Anna is not — fearless where Anna is fragile, angry where Anna is forgiving, reckless where Anna is careful. Together, they run a small bookshop and share a complicated friendship with Sarah, the one person who seems to understand them both.
But lately, things have started to change.
Old photographs show memories Anna cannot remember. Notes appear in her handwriting. Sarah insists that some of the things Anna believes about her past never happened.
And Cleo is becoming increasingly afraid of what Anna might remember.
Six years ago, something terrible happened.
Something Anna buried.
Something Cleo promised to protect her from.
Now the past is returning, one memory at a time. And as Anna begins to question everything she knows about her childhood, her sister, and the night that changed their lives, she is forced to confront a terrifying possibility:
What if the person she has been trying to escape has been with her all along?
Because some secrets need a name.
And some parts of us will do anything to survive.
