The Island Swimmer by Lorraine Kelly

When Evie's father falls desperately ill, she finally returns to the family home on Orkney.

Not everyone is happy at her arrival, particularly her estranged sister Liv. As Evie clears out her father's neglected house to prepare it for sale, she finds herself drawn to a group of cold-water swimmers led by her old friend Freya.

Together they help Evie face up to the mistakes in her past, unlocking truths that will reverberate through the community, and shake her family to its core.
