Diving In by Charlotte Watson

A decade of friendship. One reckless summer. Five years of silence.

Sam Fletcher has two constants in his life: the pool and Kath Ford. Since they met aged eleven in a busy classroom, Kath has always been his anchor. Everything that isn’t supporting his goal of becoming an Olympic swimmer is a distraction, including his terrifying, growing crush on his best friend.
Kath Ford has always made sensible choices. Colour-coded timetables. Clear goals. A carefully mapped future in medicine. Falling for Sam was never part of the plan—until one summer, when friendship starts to blur into something neither of them is ready to name.
But some lines can’t be uncrossed, and some fights can’t be resolved. Years later, Sam’s a world-famous Olympian drowning in pressure, anxiety, and the fear that without swimming, he’s nothing at all. Kath is navigating the intensity of medical training, fighting to maintain her sense of self in a world that demands everything. Both are haunted by the same question: what happens when one person gives too much—and the other never believes they’re enough?

When their paths collide again, they’re forced to confront what was left unsaid. Loving each other was never the problem—but forgiveness might be.
