I'm in the middle of checking the galleys (known these days as First Pass Pages) for the third of my Daisy Dalrymple mysteries, Requiem for a Mezzo. It's going to be reissued with new artwork next January.
Last week I was checking the first pass pages of Buried in the Country, my fourth Cornish mystery, due out in December.
I hope I caught everything, but I wouldn't swear to it. Nor can I be certain that my corrections will make it correctly into print.
It's a complicated business going from a .doc file to a book. If the end result isn't perfect, don't blame the author!
