His 2007 novel De overgave, to be translated as Someone Found, takes the subject of the 19th-century Texas Indian wars, dramatizing the story of the Fort Parker Massacre of 1836, in which a white girl, Cynthia Ann Parker, was taken as a Comanche hostage, later becoming the mother of the famous Comanche chief Quanah Parker.
The Dutch writer Arthur Japin also wrote a book, De Overgave (The Surrender), about the life of the Parker family and the loss of Cynthia Ann.
