Just finished this whole thing after a week of reading. Great story! It kept me glued to the screen! I really liked that Snape was in character while growing. It's very easy for authors to forget that Snape is bitter at his core. This characterization really kept true to Snape's personality while also exploring him in different ways and growing his character. The entire story is exceptionally well written, but the Snape parts were by far the best! I know I'll be doing a reread in the future.
