James Rollins, born James Paul Czajkowski, is an acclaimed American author known for his thrilling action-adventure and techno-thriller novels. Born in 1961, Rollins gave up his career as a veterinarian in Sacramento, California, to pursue writing full-time. His work often draws from his experiences as an amateur spelunker and certified scuba diver, leading to novels set in underground or underwater locales.

Rollins is widely recognized as a master of international thrillers, with his books translated into over forty languages and selling more than 20 million copies worldwide. The New York Times describes him as "what you might wind up with if you tossed Michael Crichton and Dan Brown into a particle accelerator together," while NPR praises his work as "adventurous and enormously engrossing."

His notable series include the bestselling Sigma Force series, which has captivated readers with its blend of scientific breakthroughs, historical secrets, and nail-biting suspense. Rollins' passion for science, history, and exploration is evident across his works, offering readers a thrilling escape into unseen worlds.

In addition to his writing career, Rollins maintains his connection to veterinary medicine by volunteering at local shelters. He currently resides in the Sierra Nevada Mountains with his two golden retrievers, Echo and Duncan, and enjoys hobbies such as scuba diving, spelunking, kayaking, and hiking.

Rollins is also the founder of Authors United, a group of bestselling authors dedicated to supporting USA Cares, a nonprofit organization aimed at helping soldiers and their families achieve financial stability and self-sufficiency.
