The relationship you've portrayed for Severus and Harry is so lovely--balanced, respectful, devoted, and yet each character is true to himself. How they handle their personal tragedy is really well-written (the range of emotions they experience, and how they try to maintain a normal life). Lastly, I really like what you've done with Petunia's character--talk about making your own bed. Sad that she recognizes where she's ended up, but is too afraid to change it. Very interesting (and, in the end, joyful) story!
