HOW IS THIS PART OF MY BOOK? HOPE YOU LIKE?

It's good, but very confusing, because it's moving way to fast, you need a little more detail in the middle so that all the names don't make the reader confused, also try rewording it a little bit, instead of "I turned a knife hit me straight in the stomach" try something like "As I turned around, I felt a sireing pain in my stomach. as I looked down I saw that Serverus had stabbed me with the blade of his knife, leaving me gasping for air, until my body's weakness came over me and I fell to the ground.
