I have finally heard back from Flux regarding my next book, tentatively titled Cupids. They want it, and we are in the process of negotiating the particulars of the contract. Based on their estimate, it should be released next spring. They are also still considering Young Nostradamus.
I finally understand why they waited so long to get back to me on this(at least, I have an educated guess). Evil? was released in August, and it is only now that the sales figures for the July - December '09 period are known. Most likely they were waiting to see how Evil? did before offering me another book contract. This suggests that Evil? must be doing all right, which is also very good news!
More details will follow once I have them. I'm very excited! My next book is on the way. Yay!
