“Come away, O human child!
To the waters, and the wild
With a faery, hand in hand,
For the world's more full of weeping
than you can understand.”

From The Stolen Child – William Butler Yeats

There are roads that are not on any map.

There are worlds beyond our own, where cities hang between the clouds and Guildships sail on steam and lightning.

There is a girl living on the streets of London, hunted by ruthless mercenaries and a boy made of shadows and smoke.

There is a place beyond the furthest edge of the Dreaming, where the Lady of The Falling Leaves is calling her home.

And there is a secret, buried in the heart of Rachael's city, that will transform our world forever.
