Lucca Advani is a regular teenage girl. Her family is compiled of eight people. Six kids is a lot, and someones bound to be left out, and thats her. She's the middle child and although she knows her family loves her she can't help but cling to things that are just hers because she's so used to sharing everything. 4th grade Lucca may have went a little overboard with cherising the little things which all changes when Theodore Adams moves into town. He never knew why she hated him and never found time to figure it out as their rivalry sprung on that first day of 4th grade. 11 years later and campus can't seem any smaller. They're in college and find themselves in each others company much more than they'd like. Will they finally bury the hatchet? Do they still harbor a childish hate towards one another? Will they finally let it go and leave room to find that there really is a thin line between Love and Hate?
