The Bad Boy Teacher and I

Enter Gabriella Hasting's world, where her parents had left her to take care of her younger brother, Mitch, after a tragic car accident. She and Mitch were later taken into Uncle Sam and Aunt Mabel's care. However, things got worse, and so she leaves the house with Mitch.
Now, enter Blake Vander, a teacher, into the picture and what do you have? Gabby and Mitch living in a teacher's house? To top it off, Mr.Vander isn't exactly what you would call a normal teacher. He wears biker jackets and has fanciful cars.
Gabby is convinced that Mr.Vander is out to make her life miserable by making her his personal maid, but is that really so?
Moreover, someone from school knows about these living arrangements and is threatening Gabby to tell the authorities about it. How can a mere 17 year old deal with all of this?
