A$$hole Stepbrother by Nicky Harmony

Tilly comes home one night and gets told that her entire life is about to change. Her mom gives her a new uniform for a fancy private school and tells her that she’ll be coming home to someplace new when she starts on Monday.
Tilly tried to get her head around everything, but when the impossibly hot guy she sits next to in science decides to knock into her so that she spills juice all down her new blouse, she realizes that even if she tries, she’ll never fit in.
When Tilly’s mother gets married, her stepbrother decides to pull a prank to end all pranks, but he doesn’t know that Tilly is still in the woods where he had just sent hundreds of fireworks on their path of destruction. The night ends in painful screams, but will he be able to make up for what he has done and will Tilly ever get over the scars that the night has left on her?
