Very good stand-alone novel from Terry Pratchett.
Two worlds collide in a timeless but all-too familiar universe.
The two representatives from each opposing culture couldn't be more different on the surface of things but become drawn to one another and find that special something that can only be achieved through trust and love, friendship and mutual respect.
A great way into Terry Pratchett's huge body of work for readers 12yo+ - next stop: Disc World!!
