Thanks for the vote of support. My winter project is an XF8U-3 monograph for Steve Ginter. I have a few "real" book projects in mind but haven't proposed any yet and may not. The first two books were relatively easy and it was still a lot of work: almost a solid year of research, making illustrations, writing, worrying that I hadn't gotten something right, reconciling conflicting reports, and rewriting for each one. Not to say that I didn't enjoy much of the process. Except for the leaving-stuff-out part to get within the contract's word and picture limit, the dog work of making sure that the pictures matched the captions and were properly referenced by number in the manuscript, and having to turn the book in without some of the material I would have liked to have included but couldn't find.
None of the possibilities that I'm interested in doing are going to be anywhere near as easy from a research standpoint. I want to be just as proud of the third one, if there is one, as the first one, which I must note was in large part due to the high publication quality standards of Specialty Press and the expertise of their layout and production departments. I'm hoping they do just as great a job on the second one.
