Hey guys I really need your help!!!

A long time ago I read a dramione book. And I want to read it again but I cleared my library and now I can't find it I was wondering if you have read it and can send me the title. This is the but I remember from it:
It's set after the war at hogwarts. 
Draco is a healer
Hermione is starting a new shop in hogsmead and it gets burnt down or atacked I don't know which one. 
Hermione goes to st mongos because of it. Draco is her healer. They rebuild the shop with Ginny Harry Draco Blaise Pansy and Astoria I think. I don't know if Rona helps rebuild her shop. But if you know a book like this please let me know
