The Book of Kallma

Elias Finch was pushed into an adventure. It all started innocently enough; a raven that used the telephone, a mysterious window hidden in a five hundred year old chapel, a missing grave, a secret brotherhood carefully concealed within another secret society, and of course, a train ride into a different dimension. No one knows just why, but the Wise Creator, Ard-Obbree, snatched up ten year old math whiz Elias Finch and whisked him off to the dimension of Kallma to find its most treasured possession - the Calba Hy, Kallma's tree of life, and save it from her most ancient and dangerous enemy, Darkon Voyd, the fallen light, and his servant, the Dark Rider.
