Intriguing main characters

There are quite a few reasons I'm interested in this story. First, I thought Autumn was an interesting character as she is in high school but seems to be running a bit of a drug empire. Sometimes the her dialogue was cheesy but at least she seems like a unique character. I'm also interested in her relationship with her sister, Ivy, and exactly why they don't appear to get along very well. Based on the publisher's synopsis I'm also curious to see where their story lines go in the future.
