I've heard a lot of bad things about those books. First I wanted to get them. Then I came on here and asked for people's opinions.
They told me they were juvenile, that a lot of things didn't make sense since it was written by people that really don't have that much to do with the show.
As it is, we have Alias magazines, the Alias Declassified book, the Alias DVDs, AllAlias.com and the SD network. That's more than enough for me... These books are short novels, prequels of what supposedly happened to Sydney before the show started.
Some of it deals with Noah Hicks, which, as Chris Rock would say, is just plain DISGUSTING!!
