About the Cash & Colcord series

CBI Agent Frankie Cash and Eagle County Sheriff Jim Colcord investigate crimes in a near-future Colorado where de-extinction science has gone mainstream -- starting with a murder at a luxury safari resort stocked with genetically resurrected woolly mammoths and Ice Age megafauna. Douglas Preston, writing in the scientific-speculation mode he also used for the Wyman Ford series, launched the series solo with Extinction (2024), his first solo novel in a decade, before co-writing the sequel Paradox with his daughter Aletheia Preston.

Paradox (2026) follows Cash and Colcord into the Colorado wilderness again, with the resort's resurrected Neanderthals now loose in the mountains and a fresh trail of bizarre killings tied to a secret society.
