Twilight Scribe Accused of Plagiarizing Other Vampire Novel

Attorneys for an author named Jordan Scott have fired off a cease and desist letter to Hachette Book Group claim that Breaking Down, the fourth book in Stephenie Meyer's Twilight series, ripped off major storylines from Scott's book, The Nocturne.
The aforementioned cease and desist letter was obtained by TMZ and claims that both books, Scott's published in 2006 and Meyer's in 2008, contain a post-wedding sex scene, a scene where the main character's wife dies and a scene about a woman carrying a demonic child with evil powers, all with similarities in dialogue. Coincidence? Obviously, Jordan Scott's people don't think so, but Meyer's people are calling shenanigans.
The claim that 'Breaking Dawn' by Stephenie Meyer somehow infringes on an alleged book by someone named Jordan Scott is completely without merit. Neither Stephenie Meyer nor her representatives had any knowledge of this writer or her supposed book prior to this claim.
The TMZ post has a link to a 15-page PDF letter detailing the alleged dialogue ripoffs. Having read through it, I'm unconvinced of any wrongdoing. You'd almost think that Scott thinks as though she's the only writer to ever include a wedding, a death and a sex scene in a novel, but go ahead and judge for yourself.
