Life from Sad to Happy
The setting in the book is very sad and kind of scary. I would change the setting to a nice snowy morning with Darren eating a lovely breakfast with Jessica and his kids after he quit being a drug dealer. I could see him being happy and watching movies with his children and wife. I think he would respond to everyone around him in a better manner because he wont be so scared that the love of his life would be in danger and his life wouldn't be so stressful. Darren cares a lot about Jessica but for the fact that he doesn't want to give up Jessica he is going to have to give up drug dealing.
