To really appreciate this story, I would highly recommend the sequel as well. It just goes to show how and why everything's a little different. Fantastic characterization all around and the author clearly planned everything out to make this a cohesive story. The only issue I find is how they try to stick to canon too much despite what they're trying to change (2nd year in particular).
Great Time-Travel story, Sequel makes it better
