When Maeve and her big sister Agnes explore the moonlit ruins of an old castle they aren’t expecting magic. But as the full moon floods the crumbling tower with silver light the two girls are pulled into another realm where the castle stands whole and glittering… and is ruled by a queen whose power is spun from moonlight itself.

The Queen has placed an enchantment on her subjects, binding them to her will. No one may refuse her. No one may leave. And now Agnes is slipping under the Queen’s enchantment too, losing herself under the spell of the moon.

Maeve has always feared being left behind. Agnes is growing up and will soon leave their island home to continue her education on the mainland. Maeve doesn’t know who she is without her sister beside her. But in a castle full of cursed courtiers and watchful shadows, it is Maeve alone who sees the weakness in the moonlight magic — and the loneliness at the heart of the Queen’s spell.

To save Agnes, Maeve must cross mirrored halls, outwit enchanted knights, and unravel a curse woven from longing and fear. In doing so, she will discover that love does not mean holding on too tightly — and that even the smallest sister can stand in her own light.
