Has Potential, Needs Work
When I started this book, i wanted so badly to like it. The beginning really sucked me in, despite being cliche. However, one thing has become infinitely clear to me after reading this far:
Read the story now
The character NEED to be stronger in order for this story to work. ALL OF THEM.
I'm not talking strong as in tough or bada**, I'm talking strong as in they need to be fleshed out and developed. Everything so far has been plot driven (Rebekah hasn't made ONE decision for herself yet - everything happens to her and she just reacts. She needs to be active, not reactive.). The characters just feel 2 dimensional, mostly because they're built on stereotypes, ESPECIALLY the women characters (hint: if the other females in the novel need to be vapid and stuck up (Scarlet, Lizzie, Mom, every girl that Rebekah goes to school with) in order to make the main character likeable, your main character isn't likeable enough).
this is what leads Rebekah and Marcus have so little chemistry, because we as the audience have NO IDEA what makes them tick, let alone what they would see in each other.
What I would suggest you do is sit down with some character sheets and figure out who everyone in this book is, and how that would lead them to interact with each other. What do they do? How do they do things differently than other people? How do they talk? What will they say? What WON'T they say (this is especially important. The characters sometimes overinform each other for the sake of plot. Don't have the characters say things they wouldn't say as people.) The plot can work, but the plot will continue to feel stilted until the characters are driving it.
I don't mean any of this in a harsh or mean way, I just want to see you improve your craft and story. If you want any help or any more advice, feel free to ask me!
