If you want to tell reading-skeptical kids about "the volta", please don't phrase it as "the volta". Just say that a lot of good novels need you to read them for a bit to see what's going on, and then it will get good. They might already be familiar with the idea from TV shows.

But also, it's extremely possible to write a novel that grabs you from the first page. Thriller writers are the most obvious case. A gripping concept or setting can do it, too. This author might think they're too cool for books like that, but we shouldn't keep them away from kids if that's what they want to read.
