Aikido and the Dynamic Sphere. I have found it very insightful, if a little difficult to read (reasonable technical language and words I cannot pronounce..) and there are some diagrams of technique, which is nice.
That was my first book also, and I still like it. It is a good read that gives an overall look at Aikido in general. I would say if I could only have one book, that would be it.
But I also like Principles of Aikido (Saotome) and Total Aikido (Gozo Shioda), although I don't practice Yoshinkan Aikido, Total Aikido does a good job at describing some of the inner mechanics involved in technique that other books do not.
