I've just recently gotten back to where I can probably manage my normal writing schedule (one chapter of 4-5 thousand words per day, 5 days a week, for those curious) and keep it going again. I am already more than halfway through writing the book, so I should manage to finish writing it in June, but between proofreading, editing, and all the other after-writing portions of publication it won't get published until July.
My apologies to all for the delay.
Tom
