What would I do if an editor didn't publish my manuscript? My paper was accepted to be published as a chapter in a SPRINGER book after it was presented at an IEEE-sponsored conference and gaining a high score form their peer-reviewers. The editor of the book series (also the chairman of the conference) invited me to submit an extended version of the paper (at least 30% of new ideas) so, I emailed the final manuscript but didn't get any feed-back until I figured out that the book is now available online but the title of my article doesn't appear in its table of contents! I asked the book editor about this issue but still haven't gotten an answer.
Based on your timeline, my guess is that your email didn't reach the editor. Perhaps it went into her spam folder, or he saw it and then forgot about it, etc. There's little chance this is malicious. After all, the editor has nothing to gain by holding your manuscript unpublished. Now that the book's been published, there's no chance of inserting your manuscript into it either.

You've already emailed the editor, which is all you can do. At least it'll make clear where the error was, and more optimistically, perhaps the editor will find somewhere else to publish your manuscript. It's all you can do, and next time, you can ask the editor for a confirmation of receipt if you don't hear back from her after a while.
