The Warrior in My Wardrobe: Simon Farnaby

Merdyn is the greatest wizard of the Dark Ages. Obviously.
Rose is his 21st-century descendent. Lucky her.

And Vanheldon the vandal warrior is Furious! After all, last time they met, Merdyn turned his army to stone.

Seeking revenge, Vanheldon comes up with a way to kidnap Rose and transport her back to Dark Ages Transylvania, set on luring Merdyn into a terrible trap. Except - whoops! - his magical minion kidnaps Rose`s teenage brother Kris instead.

Rose, Merdyn and Bubbles the guinea pig must team up to save the day. But can they rescue Kris without creating historical mayhem? Will Rose`s wizard ancestor even remember her? (And want to help them?) And will Bubbles ever stop pooing?
