A very nice book written by William Stuart for Young Adults. It tells the story of Aiden an Maggie discovering the magic world of fairies and elves and the story has a similar feel and atmosphere as the Narnia tales. Aidan and Maggie find a fairy cross while rock-hunting with their grandfather, it's just an oddity. But when they discover there is an elf imprisoned in the stone and set him free, they and their grandparents, Nana and Beebop, are attacked by some other elves and have to flee to the magical world of Celahir.
In Celahir, Findecano - the elf the children freed from the fairy cross - leads them on a quest to recover gemstones stolen from the Elven Bow by the Dark Elves. Without the restoration of the gemstones to the Elven Bow, the balance between good and evil in Celahir - and the human world - could tip toward evil.
I really enjoyed this book. There is some very passages that made me laugh. I think most teens will enjoy the mystery of the story and I would highly recommend this book.
