Moon Island (Abridged ed)

On the coast of Maine, five old clapboard houses gaze out to sea.

When fourteen-year-old May Duhane arrives for her summer vacation, following the death of her mother, she feels isolated and resentful.

Her elder sister is interested only in the local boys, and her father is attentive to a married neighbour.

Then she discovers the diary of Doone Bennison, a young girl who died in tragic circumstances on the island the year before.

It is clear from the diary that Doone had a passionate crush on someone she doesn't name, an attachment that may have cost her her life. And as events during the summer unfold, May begins to feel she is destined to follow in Doone's footsteps.
