Deeper Than Blue by Jill Hucklesby

Amy is thirteen and a swimmer, the book opens with a vivid breakthtaking passage of her taking the county record from another swimmer she has admired and tried to live up to. A spectator drops their glasses and the shattered pieces fall into the pool, meaning the pool has to be drained and Amy, for the first time in years, doesn't have to go to training so she goes shopping with her best friend Sophie but a tragic set of events leaves Amy grieving and damaged. Coming back from deeper than blue is a long road for Amy, accompanied by the adorably quioxitc Harry, her family's move to a new life in Brighton and her dog. Beautifully written and plotted, deeply moving and intelligent, a real pleasure to read.
