Earth is Turning

Callie O'day is 18 years old. Her parents are making her marry an old friend from high school, Justin Parker. Justin's family owns a mansion and several vehicles, including a private jet, a helicopter, a limousine, a convertible, and a yaht. This should be a dream for Callie, but she has a terrible past with Justin. Then, to add to her bad luck, she meets Levi, Justin's younger adopted brother. She falls madly in love with him. Levi is 21 years old and a divorced dad. He has four irresistible children: 4 year old Julie, 10 year old Stephanie, 12 year old Brandon, and 14 year old Mackenzie. What will Callie do when she's torn between worlds, and will her past with Justin come back to haunt her?

(Sorry if my updates are really, REALLY slow... I usually get bored with stories and it takes me a while to get more ideas for it.) ;) also, I know that the ages of Levi and his kids aren't right, but just pretend they are.
