The Ghastly Exchange and Other Tales. The Wandering Castle, #1

Castles tend to stay put. They don't usually hop from one world to the next every fortnight. But due to a freak magic accident, that's what Castle Silverhill, and everyone in it, has been doing for the last eight hundred years. The trouble is, the current lord of the castle can't keep his big mouth shut and it inevitably lands him in dire straits when he's out and about in the worlds the castle's visiting.
If only he hadn't skipped all those magic lessons when he was a boy, he'd know the right spell to get himself out of his self imposed messes. If it weren't for his goblin sidekick, Grimmon, and Trewla, an elf he's secretly in love with, he'd long ago have ended up in the belly of a dragon, or executed by fairies, or beheaded by a knight, or squidged by a giant. But when a vampire steals his mind in order to take over the castle, even his friends might not be enough to save him. This collection of five tales is a humorous fantasy featuring an antihero with more hubris than you can shake a wand at, a long-suffering but cynical sidekick, and a slow-burn incompetent romantic pursuit arc. Don't get left behind!
