If you like fantasy novels and cats then this is the series for you. Currently there are 3 books in it; Summon the Keeper, The Second Summoning and The Long Hot Summoning. The books are by Tanya Huff who is a Canadian writer and the books are set in Ontario Canada for the most part. Her talking cats (similar to familiars) really make me glad my cats can't talk - they have enough attitude without verbal ability. It is a well written series.
