The story has kept me interested so far, but it'd be easier on the reader if you broke up the paragraphs when there was dialogue. For example in chapter three, the first paragraph would be easier if you had it:
Matt and Zacky had finished painting Sophie-Anne’s bedroom, it was pink and wonderful according to Sophie-Anne. She knew that it would be an amazing room.
“Daddy? Can I please have a glass of milk?” She asked quietly. Matt rushed down the stairs to retrieve a glass of milk for his niece. He really does want to spoil her. After five minutes he returned with a glass of milk and cookies for little Sophie-Anne.
“Trying to be the best uncle?” Zacky laughed. Picking Sophie-Anne up. Gena walked into the room and sneered at the little girl in Zacky’s arms.
“Honestly. I don’t understand why you don’t like her.” Zacky snapped at Gena.
“Why should I like her? She’s not mine.” Zacky’s anger flared up. How dare she say that about his daughter.
“Get out of Sophie-Anne’s room! Now!” Zacky roared at Gena causing Sophie-Anne to cower, hiding her face in her dad’s shoulder. Gena stormed out of the room.
“I’ll be at Val’s if you want me!” She yelled before slamming the door. Sophie-Anne had started crying.
