Guardian Hostage Rescue Specialists: Delta Team follows the organization’s Delta squad through their operations. Starting with Rescuing Aria (2025), the series adds another layer to the expanding Guardian franchise.
The six-book Delta Team series is the newest addition to the Guardian HRS world. Some character names appear across multiple team rosters, which is typical of Ellie Masters’s approach to the franchise. Rescuing Ember (2024) is one of the available entries with a confirmed ASIN.
Delta Team is best read after the earlier team series (Alpha, Bravo, and Charlie), since the Guardian organization’s backstory and recurring characters will be more familiar. However, each book still follows the same standalone romance structure, so new readers can pick up individual titles without being lost.
