Sisterhood by Cathy Kelly

Two sisters. One secret. A journey to learn who they really are…
As the waves crash on to a wild Atlantic beach, Lou is at a crossroads. For the first time ever, just giving up seems like an option.

In just one night, at her own 50th birthday, her world has imploded. Her mother has kept a secret hidden all her life. And it changes everything. Before Lou can take another step, she needs to get to the bottom of the shocking truth that alters who she really is.
Along with her sister, Toni, who is facing her own crisis, the two women sets out on a life-changing journey – one that will take them through Ireland’s wildest coastline and to Sicily’s sun-baked rocky shores. It will also take Lou deep into her relationships with her mother, her sister and her daughter to figure out how to stop pleasing everyone else – and carve out who she really wants to be.
