I just finished my second most stacked narration project (Middlemarch)
320k words, absolute behemoth of a gig, but it's practically complete. Just need to master a few more files so its ready for ACX. I will admit, I do have periods of laziness and without those It'd have taken a month or so, but it took me about two. I thought posting this might act as a good reason to maybe give advice to people who feel intimidated by the size of some narration gigs, or moreover, narration gigs that also require vast amounts of character acting. Remember, it's possible, and you can do it!
