Arc I (Chapters 1 - 11) introduces the character of Rebeeca Swansin (whose friends call her Moon), Bella Swan's cousin, who recently moved in with Bella and her dad in Forks. Rebecca is an "enviyournmentalist" who... Doesn't really do all that much besides hate on Bella and talk to Edowird. The other characters, however...
Arc II (Chapters 12 - 22) picks up dealing with the next week of life at Fourks High following Rebecca's murder of her uncle, Charlie. The school is invaded by riot police and quarantined for unknown reasons. Meanwhile, the once-human Angela tries to claim Bella's life.

Break the Cutie: Bella Swan. Raped, mistreated by her cousin, her best human friend in canon turned into a vampire, who then killed all her other friends (except, oddly enough, for Mike), shot, and gets her truck vandalized repeatedly by Rebecca, who then brutally murders her father and forces her to live in a shed, where she's forced into prostitution in the sequel.
Groin Attack: Rebecca's use of an "anti-rape knife" might or might not have resulted in this.
Guns Akimbo: Rosalie becomes this in chapter 14 when she starts a firefight in the school against a few cops and begins to take on legions of SWAT team members as the school gets invaded.
Gun Fu: It feels like absolutely every single character in this story is trained in professional firearm usage.
Perhaps even more ludicrous is just how every single character has a gun on them at all times, even if it makes no sense for them to have one. In her first appearance, even Clarity Etude Simphonia takes out a gun, despite her having vampire powers that would eliminate any need for keeping a gun on hand for self-protection.
After chapter 16, Rebecca begins to use one in combat as well.
Karma Houdini: Rebecca, considering all she's done throughout the series and especially for what she does to Charlie.
MacGuffin: The "vyle" which Rebecca must take to the Principal's office towards the end of chapter 19.
Made of Iron: Bella can be shot fourteen times in a row, survive it, and be out of the hospital in a matter of hours.
Maybe not as strong of an example, but in the final showdown, Rebecca takes seven shots to her arm while fighting Charlie and doesn't even flinch. She never mentions going to the hospital afterwards either, implying that she just walked around for the rest of the day with those injuries without ever getting them checked.
In Arc III we're introduced to Clarity Etude Simphonia, who's only characterization is that she's Rebecca's old friend.
Out of Character: Oddly averted with Edward and Jacob, as an argument can be made that they retain their devotion from the original series. However, Alice, Jasper, Rosalie, Angela, and Charlie are all massively out of character.
Protagonist-Centered Morality / Double Standard: For instance, Rebecca follows a hot guy in the boys' locker room, accuses him of being a pervert for "flashing her" — while he had actually not even noticed her — and uses her anti-rape knife against him, then when a whole bunch of guys get out of the shower to see what the commotion is about, she accuses them of attempting to rape her.
Purple Prose: We have several examples, but this one from chapter 10 fits the bill the most:
