Gregor The Overlander

I'm reading a book in my English class and it's called 'Gregor The Overlander' In the beginning of the story Gregor has said that his dad had run away. Gregor is now the man of the house. He has two little sisters. One is 7 years old and the other is 2 years old. the 7 year old is named Lizzie and the 2 year old is named Margret but they call her boots. Gregor lives with his two sisters, grandma, and his mom. His mom is a hard worker. One day Gregor and Boots his little sister were doing laundry.
