The first book written in the Origami Bonsai series was "Origami Bonsai" which is published by Tuttle and will be available in November of 2009. The second book in the series, "Advanced Origami Bonsai" was published electronically on June 1, 2009.
It's a little confusing, because the second book was published before the first. This works out better for origami bonsai artists because the second book teaches Makigami, a method for making plant stems and branches by rolling paper. So if you buy "Advanced Origami Bonsai" you'll be an expert at making plant branches when the really intricate flowers in "Origami Bonsai" become available.
