The Lost Girl King | Catherine Doyle

Amy and Liam Bell are sent to spend the summer at their grandmother’s house in the remote wilderness of Connemara. On the first morning of their stay, they follow the flight of a hawk to a nearby waterfall—only to watch it vanish through the cascading water. Curious, they step forward and soon realize they have stumbled upon the entrance to Tír na nÓg, the legendary land of eternal youth.

But it’s a trap. Almost instantly, Liam is seized by a group of headless horsemen and taken to Tarlock, the sorcerer who rules Tír na nÓg. Tarlock has dark intentions—he is searching for the bones of a human child to complete a powerful and sinister spell.
