The Delta series follows a covert military team through six novels published between 2014 and 2019. Each book focuses on a different team member and pairs their mission storyline with a romance. The titles all begin with “R,” from Retribution through Ricochet.

The series is connected to Harber’s larger Titan world. The Delta team operates in the same sphere as the Titan operatives, and some characters cross over between the two series. The military action is intense, and the romantic relationships develop under extreme pressure.
