Delta

Cristin Harber is a New York Times and USA Today bestselling romance author with a proven military romantic suspense readership, and the premise of 'Delta: Retribution' has real emotional stakes — a Navy SEAL grieving his twin brother who then discovers his one-night stand has become his black-ops mission target. The tension between duty and personal loyalty is the kind of setup the military romance genre does well, and Harber delivers the action-romance blend her fans expect. That said, Penny has to be straight with you: both the author and reviewers describe this book as explicitly sexual and steamy. Graphic content puts it firmly in adult-only territory and makes it a poor fit for faith-conservative readers or anyone looking for clean romance. For adults who enjoy the genre without those restrictions, Harber is a skilled and popular practitioner.
