The Aces series follows a group of elite protectors and security professionals. Each book pairs a different operative with a love interest while they navigate a dangerous mission. Published between 2018 and 2025, the series has grown to seven books.
The series shares the same connected world as Harber’s Titan and Delta books, giving returning readers familiar touchpoints. The protective hero trope runs through every entry, with each book offering a self-contained romance within the ongoing security world.
