The Delos series launched in earnest in 2015 and ran through 2018, with Lindsay McKenna publishing a substantial number of books in a short window. The Delos organization itself is a private security company whose operatives range across international hotspots, and each book follows a different pairing from within or connected to that world. Last Chance, Nowhere to Hide, Forged in Fire, and Tangled Pursuit all appeared in 2015 and established the series quickly.
The pace picked up further in 2016 and 2017, with McKenna releasing multiple Delos books each year. Titles like Broken Dreams, Hold Me, Hold On, Blind Sided, and Unbound Pursuit fill out 2016, while 2017 brought entries including Never Enough, Dream of Me, Trapped, Taking A Chance, and The Hidden Heart. The series closed out in 2018 with Boxcar Christmas, Sanctuary, Dangerous, and Redemption.
Delos has similarities to the Morgan’s Mercenaries world in its use of a private security organization as the backdrop, but the books read as more modern romantic suspense with a global scope. Each entry is largely standalone, though recurring organizational elements appear throughout. Last Chance is the best place to start for readers picking up the modern Delos series.
