One of the worst books I’ve ever tried to read. But I wasn’t getting paid to read it, so I stopped.
In writing dialogue, especially in a fantasy or a historical novel, there has to be a happy medium between “I feel ya, dude” and “Yea, forsooth, thou barkest up ye wrong tree.” That happy medium is plain English.
Yes, I know–tons of books have been published in which plain English is simply not to be found. Some of them have even been best-sellers. But that doesn’t make them any less abominable.
Someday our age will be called to account for Robert Ludlum and Jean Auel; and it won’t be pretty.
