No one got them all right.
But the answers are now on the original posting.
Did you just talk to one publisher or something? Seems like you should just decide which book you want to do, write up a proposal, and find a publisher (or agent) who likes the idea. You don’t have to work with the same publisher who put out your first book. I guess you probably know that, but I figured I’d say it anyway in case you hadn’t thought beyond your current publisher.
Not bad; the two I just knew were real were in fact real.
