YES, the title changed.
Long story very short: trademark trolls. Title wasn't the same. Genre wasn't the same. Prior use all over the place ... but some people have a vested interest. I will not publicize this because quite frankly, the less time I have to spend dealing with this the better, but I felt at the very least there ought to be some word for those of you who haven't been following the drama in other channels. Could I have fought to keep my original title? Yes, yes I could have. Why didn't I? Math. One has to know when to hold em, and when to fold em.The time and money I'd have spent on it would have outstripped any possible fiscal return, and since this is only one book title rather than the name of the series, it doesn't really impact my branding. Nothing about the story or its contents has changed, other than the title. God Willing, this is the last I'll have to hear of or deal with this sort of nonsense.
