this is my favorite book in the series thus far.
Sirius' letter to harry in the end is so heartwarming. And Lupin.. ah I just love him so much. Can't believe I thought he'd turn out to be Voldemort's spy. 
Harry is reunited with his dad's best friends. It's so heartwarming.
His patronus is his dad's animagus form. Harry is the spitting image of his dad. 
My heart is full
