John Stephens - The Emerald Atlas

"The Emerald Atlas" by John Stephens is the first book in the series of "The Books of Beginning". Ten years on, Kate, Michael and Emma have grown up in a string of miserable orphanages, and all memories of their parents have faded to a blur. Arriving at Cambridge Falls, the children quickly realise there is something different about this place - and Kate feels sure she has seen the dark, crooked house before.
