I've read all of the books by S.D Perry, they're a really nice read. I like how she's inserted some of her own made up plots in a few of them. My fav would have to be Nemesis, I really like how she went away from talking about Carlos and Jill and gave readers an insight into Nicholai and what he did when not with the rest of the party.
Although readers should look into too much on what she writes, as not all of it is offical to the story, but none the less it's still builds on the orignal story at the end of the day.
I'd recommend any Resident Evil fan to get ahold of these books, they can be found on ebay and Amazon. I bought a few of mine from a oxfarm shop, of all places and the rest on amazon, some from the U.S website.
