The Sister Effect (Paperback original)

The brand new romance from New York Times bestselling author Susan Mallery

No one knows you better…

Finley McGowan lives her life by 'rules'. Rules give her stability and stop her being hurt, something she needs more than ever after her sister's betrayal years before.

Sloane McGowan spent her childhood trying to be the perfect daughter and sister. But when one traumatic event derailed her life, she found it spiralling out of control, until the fateful day she betrayed the one person she loves most - her sister.

When Sloane reappears in Finley's life wanting to make amends, Finley must decide what is more important - rules or family? And, if the past is worth letting go, in order to embrace a future.
