Silent reading the end of my book

Today I have finished Monster blood and this is what I have found out that Sarabath was a evil witch but she never showed it because she needed the Monster blood so when Evan found it she needed it ( Sarabeth not Andy )  But the reason why was because Sarabeth put a spell on it but when Aunt Kathryn  found out Sarabeth was doing Black Magic she started fighting her but Sarabeth touched the monster and got turned in to a cat and just before that she made Kathryn deaf but they beat her because Tigger scared her to the Monster blood and that is the end of Monster Blood
