The Last Dragonslayer 
The Song of the Quarkbeast
These are two really good books-if you can suspend your disbelief and just go with it! Jennifer Strange is the acting head of KAZAM, an agency that employs sorcerers & wizards in the semi-magical world of the UNunited Kingdom. The last dragon will die on Sunday at the hands of the last dragonslayer, then the world will change and magic may either come back to the world or die forever. The Song of the Quarkbeast continues the tale of KAZAM as the King tries more underhandedness and some things may be resolved with the Great Zambini. Everything is wrapped up in the end with humor, magic, violence and fun all the way through. Fforde writes the quirkiest books and these are two of the best.
