The thrillers of Douglas Preston and Lincoln Child “stand head and shoulders above their rivals” (Publishers Weekly). Preston and Child’s Relic and The Cabinet of Curiosities were chosen by readers in a National Public Radio poll as being among the one hundred greatest thrillers ever written, and Relic was made into a number‑one box office hit movie. They are coauthors of the famed Pendergast series, and their recent novels include The Cabinet of Dr. Leng, Diablo Mesa, Bloodless, The Scorpion’s Tail, and Crooked River. In addition to his novels, Preston is the author of the award-winning nonfiction book The Lost City of the Monkey God. Child is a Florida resident and former book editor who has published eight novels of his own, including such bestsellers as Chrysalis and Deep Storm.
