Brannigan’s Blackhearts is Peter Nealen’s longest series at fourteen books. The team of military veterans takes on mercenary work across the globe, from Kill Yuan (2016) through Legacy of Terror (2024), handling jobs that range from hostage rescue to counter-terrorism.
Nealen’s Marine background gives the series authentic tactical detail, while the mercenary setup lets him send his characters into conflicts that official military fiction can’t easily explore. The Blackhearts operate in a moral gray zone where getting the job done matters more than following rules.
