|Book Two, His Dark Lady, will be out in paperback soon in the UK|
At copyedit stage in a major publishing house, the writer works with a copyeditor on the final manuscript. Continuity and timing are checked, place names verified, general logistics questioned, and of course anything which jars and catches the copyeditor's attention gets a once-over by the writer.
Changes may still be made at this stage, but they are unlikely to be much more than cosmetic - a paragraph may be rearranged or rewritten, individual words may be deleted or added, and occasionally other work may be suggested. But any larger revisions - changes to the plot structure or character development - should already have been done to the editor's satisfaction.
All that remains after this stage is proofs: a final check that nothing has been missed, then on to the printing stage!
Her Last Assassin will be out in hardback in early 2014. Cover reveal coming soon!
