Judi there is only one book and that is the Dear Jane book. This is a good site for helpful hints on making the quilt and she sells the book too Anina from Twiddletails -
http://thatquilt.blogspot.com/ I have ordered from her and always had good service.
Also if you go to the original Dear Jane site, Brenda sells the rulers, freezer paper and the book and software if you want to go that route. Brenda can be slow at times sending things but has a good reputation too.
http://www.dearjane.com/ go to the side bar and look at the store items.
good luck :)
