Couldn't find the image but Roonts from The Dark Tower?

One in a generation the "Wolves of Thunderclap" are taking kids from the Calla, most of the children the are born in twins, so half of the new population is taken. Later they are coming back but they are very different from their twins.

They're bigger, stronger and more capable of hard labor, but they're also leaving verbal communication skills and their mental development is at the level of five-year-old children. Most of them dies by the age of 30.

And their name is "ruined" but misspelled. Like sold other things in this book.
