The Traitor King — Todd Mitchell

A fast-paced fantasy/mystery involving Celtic mythology for ages 9 & up (Colorado Book Award Finalist). Darren and Jackie Mananann have always known there was something a little strange about their family . . . but it isn't until an unexpected presence propels them into a fantastical mystery that they discover how truly unusual and eerily powerful the Mananann family is. Things that once seemed ordinary -flowerpots, librarians, plates of cookies- suddenly have extraordinary meanings. And places that once seemed safe -trees in the forest, a fireplace in the den, a secret passage- are suddenly no longer safe. One of Darren and Jackie's uncles has disappeared, and in order to save him they must unravel all the clues and signs that surround the Manananns's deepest, darkest secret -a secret that spans two very different worlds. For the Manananns, mystery runs in the family. But where will this mystery lead?
