Well, that threesome was a bit different. Actually, a whole lot different! Plot was interesting. Another of those differences. The wandlore was thought-provoking and very original (I'm assuming you made all of that up.) The relationship between Draco and Harry, Draco and Severus, Harry and La Weasley were well thought out and, frankly, closer to what I think of as canon. (I thought Luna was a better match for Harry than Ginny anyways. Draco will do as well.)
I love the maturity that Draco has gained. It was logical, based on his life experience.
All round, a great read, and one to be reread often. empathic_siren's gift is ours as well.
