I was initially skeptical about these books. At first glance they appeared to be trying to cram way too much into them. Spaceships, magic, vampires, werewolves, aliens, sentient inns with dimension-warping capabilities, etc etc.
But damn, they're entertaining. And I think this one could be my favourite in the series. The first three told from Dina's POV are great, but in this one, the POV switches to Dina's sister Maud. And she is seriously kick-ass. I was cheering for her all the way through.
