The Cave of Secrets by Morgan Llewellyn is a story about Tom Flynn, the rejected son of an indebted land owner. One day, running from his father’s temper, he stumbles across a cave in Roaring Water Bay and there he meets Donal, who is different to Tom in every way. While Tom has been raised in a big house without any friends, forbidden to go to the bay for fear of “savages” and learnt only about England, Donal has been raised with the sea at his fingertips, part of a large family and has spoken Irish since he was born.
