I've been asked about it because the books include werewolves who are Native. Quileute, to be precise, from the La Push reservation in Washington. Quileute is not made up, and neither is La Push. Both are real.
I read the book, quickly. Here's passages that begin on page 124. The Quileute boy, Jacob, is with the protagonist, Bella, on an outing. Bella's love interest is a guy named Edward Cullen. Bella suspects Edward is different (doesn't know yet that he's a vampire), and is trying to get information out of Jacob. I'll start with Bella speaking to Jacob, and his reply:
"What was that he was saying about the doctor's family?" I asked innocently.
"The Cullens? Oh, they're not supposed to come onto the reservation."
Jacob feels he's said too much, but Bella promises she won't tell anyone. Assured with her promise, Jacob goes on, saying:
"Do you know any of our old stories, about where we came from--the Quileutes, I mean?" he began.
"Not really," I admitted.
"Well, there are lots of legends, some of them claiming to date back to the Flood--supposedly, the ancient Quileutes tied their canoes to the tops of the tallest trees on the mountain to survive like Noah and the ark." He smiled, to show me how little stock he put in the histories. "Another legend claims that we descended from wolves--and that the wolves are our brothers still. It's against tribal law to kill them.
"Then there are the stories about the cold ones." His voice dropped a little lower.
"The cold ones?" I asked, not faking my intrigue now.
"Yes. There are stories of the cold ones as old as the wolf legends, and some much more recent. According to legend, my own great-grandfather knew some of them. He was the one who made the treaty that kept them off our land." He rolled his eyes.
"Your great-grandfather?" I encouraged.
"He was a tribal elder, like my father. You see, the cold ones are the natural enemies of the wolf--well, not the wolf, really, but the wolves that turn into men, like our ancestors. You would call them werewolves."
"Werewolves have enemies?"
I stared at him earnestly, hoping to disguise my impatience as admiration.
"So you see," Jacob continued, "the cold ones are traditionally our enemies. But this pack that came to our territory during my great-grandfather's time was different. They didn't hunt the way others of their kind did--they weren't supposed to be dangerous to the tribe. So my great-grandfather made a truce with them. If they would promise to stay off our lands, we wouldn't expose them to the pale-faces." He winked at me.
Jacob goes on, eventually telling her the cold ones are vampires. Then he says:
"Pretty crazy stuff, though, isn't it? No wonder my dad doesn't want us to talk about it to anyone."
I couldn't control my expression enough to look at him yet. "Don't worry, I won't give you away."
"I guess I just violated the treaty," he laughed.
"I'll take it to the grave," I promised, and then I shivered.
"Seriously, though, don't say anything to Charlie. He was pretty mad at my dad when he heard that some of us weren't going to the hospital since Dr. Cullen started working there."
"I won't, of course not."
"So do you think we're a bunch of superstitious natives or what?" he asked in a playful tone, but with a hint of worry. I still hadn't looked away from the ocean.
There's more as the book progresses, but none of the reviews mention the werewolf/Quieluete material...
More later. (And if you've read the books, please comment.)
