Summary: Severus Snape, dangerously embroiled in his duties as Dumbledore's spy, encounters yet further obstacles when he begins to harbor feelings for a sixth year Gryffindor student. Succumbing to his desires sets in motion a chain of events that could very well destroy all that he and the opposition of Lord Voldemort have striven so hard to accomplish. Please keep in mind that this is written from the angle that Snape is no longer a follower of Voldemort, and that its events coincide with books 4, 5, and 6, with a slight continuation beyond HBP. (Chapters 1-15 need some fixing to work with Book 7.)
