Since I had received rejections from so many publishers, I submitted Witchery to Double Dragon Publishing, the same one that published Prophecy of Honor. I received an acceptance e-mail in less than a week, and I've now signed the contract.
But here's a funny thing: Back in March I submitted the total manuscript to a small press publisher. Their website predicted a 2-3 month waiting period. In late July I sent them a follow-up inquiry but received no reply, so I just figured they weren't interested. Just a few days after I received DDP's acceptance I got an e-mail from this publisher. They were going to start reading it but wanted to know if it was still available.
I explained that the manuscript they had was no longer valid because of the massive edit I'd done since, and that they were just over a week too late.
As soon as Witchery has a scheduled publication date I'll post it here and on Facebook.
