for The Humming of Numbers by Joni Sensel
Aidan is poised to take his monastic vows-until a girl enters the abbey, one who hums of the number eleven. Aidan has the ability to hear the humming of numbers, a buzzing energy given off by living things. He is captivated and tormented by the mysterious girl, Lana, who has some unusual abilities of her own. How can he become a monk when his mind is filled with impure thoughts? Before he can begin to sort his feelings out, the Vikings raid. Only Aidan and Lana can save the village from certain, violent death-and only if they learn to trust in their mysterious talents. Joni Sensel's richly imagined new novel is a compelling blend of fantasy and adventure. The Humming of Numbers is a 2009 Bank Street - Best Children's Book of the Year.
