For the last 5 years (delayed partly by teaching, a parent's death and caregiving for another parent), I've been writing a textbook that examines a famous 18th-century political work. The proposal was accepted and a year later, I got very positive feedback on the first half of the manuscript.
I finally submitted the entire manuscript in early December 2018 and felt quite confident about it--despite the fact that my Ph.D. is in English literature and not history or poli sci. I wrote to the editor back in late January to see if he'd gotten any word; he replied that he hadn't heard anything and to wait until late February. I've been writing to him once a week since then--and twice last week, but with no luck. It's strange because when I was corresponding with him back in August-December, he always answered very promptly.
I've tried writing to the editor who approved the book proposal (he's since moved onto another department) and another who was a supervising editor. No response. I am really stumped: what can I do since I cannot seem to reach anyone at all? I realize there's not much action I can take and that there are any number of scenarios (maybe none of the reviewers liked it and they are sending to others?), but it is really driving me up a wall. I've looked up the "Contact us" section in the publisher's website, but there is no information on the editor of the textbook for the series that I am editing. There are no phone numbers either. Any advice?
