I am looking for the name of a fantasy book that I read a few years ago, its about a boy who lives in England during one of the world wars. His mom dies and his dad re-marries and they have a kid, he resents the kid. He then enters a mythical world where all the fairy tales are somewhat askew and he has to find his kid brother. Any ideas?

The Book of Lost Things?

Thanks SOOO much Dude!! I would Never have guessed it in a million years!~

Glad to help.
