I loved Enterprise, but I hate the relaunch books. I recommend Daedalus and Daedalus' Children, set toward the end of season 2. I thought they were great. Just don't judge all the 500+ novels bad if you dislike the first one you try, ok? Oh, and if you like DS9 you've got to read A Stitch in Time. Garak's life story written by Andrew Robinson himself. It's standalone, and 100% awesome.
