1) Choices 2) The Treacle Tart 3) http://www.fanfiction.net/s/1373251/1/ 4) A beautiful story about Snape and Lupin needing to choose whether to keep to the status quo, or to take a chance on love and risk being hurt. I've read this one over and over, and I always sigh with satisfaction at the end.

Lupin wants to adopt an orphaned Death Eater's son, but the Ministry doesn't let werewolves adopt, so Snape adopts the boy and they raise him together. The adopted son, Jasper, is an interesting, well-rounded character, and not overly cute or bratty.
