Query: A witty, wry little masterpiece.

Poor Jill, who is our protagonist. She is just minding her own business one day at work in the used bookstore, and suddenly a dwarf comes in and her life gets a lot more complicated (to say the least!). Jan Banbury is an extremely talented writer. No one else could have woven such a complex mystery into such a funny, delightful read.
