All aboard for a magical journey...

When Suzy hears a strange noise in the middle of the night, she creeps downstairs to find a train roaring through her house. But this is no ordinary train. This is the magical delivery express for The Union of Impossible Places.

Whisked onboard by a troll-boy, Suzy's world is turned upside down when she's asked to deliver a cursed package to a fearsome sorceress. And quite suddenly, Suzy realizes the fate of the Impossible Places is in her hands...

Except when the mysterious package begs not to be delivered, Suzy discovers the fate of the Impossible Places might just be in her hands...
