The Cybils Awards panelists were curious about Angelfall's editing process because they thought it was well edited. So I thought I'd post my answer here in case any of you were interested.
Angelfall went through two rounds of beta readers and 2+ rounds of copyediting.
When I "finished" the manuscript, I sent it out to four beta readers. I revised based on their comments and then sent it out to two additional beta readers. I revised again based on the second round of feedback. That was my story editing phase. Then came the copyediting phase.
The manuscript was combed over by a volunteer who offered to copyedit. After that, I did another round of copyediting myself and one of the early pre-publication readers caught a couple of copyediting issues as well. Then the book launched to the general public. Within the first week, a couple of minor issues were pointed out by generous readers and I immediately fixed those.
So Angelfall had a team of fabulous volunteers who helped with editing and you can find them in the Acknowledgements section of the book.
