If you already pay for Kindle Unlimited, you can read any of these books for no additional cost. If you don't, the 30-day free trial covers the whole catalog. Either way, here's the easiest way to find the right series to start with.
The big series
World on Fire
Three books plus a prequel. Paranormal thriller, demon hunters, a haunted Pennsylvania farmhouse, and the trilogy that put me on Amazon's map. Start with Raven's Peak and you'll know by chapter three whether this is your kind of book.
Last Light
Nine books, science fiction horror, a corrupted lunar base, and a researcher named Kate Morrison who is in deeper than she knows. The series I have been quietly building for two years. Last Light in the Dark drops June 15, 2026. Interior, slow-burn, cold.
Graveyard of Empires
Military science fiction across a sixty-thousand-meter space station with the bones of a dozen dead civilizations inside it. Four books, completed.
World of Shadows
Three books, supernatural horror, a priest with a complicated past and a Vatican that has been hiding worse things than anyone wants to admit. Start with The Everett Exorcism.
The Ashen Kingdoms
Grimdark fantasy where the empires are the villains, the gods stopped answering a long time ago, and most people are still trying to be decent inside the wreckage. Four books out, fifth in revision.
The Covenant Files
Five books, urban fantasy noir, first-person present-tense. A demon hunter who narrates her own job the way an honest detective would, with the dark humor of someone who has had to lie to a priest about what she does for a living.
Verada Requiem
Five books, dark fantasy, a fallen empire, three siblings who all believe they are the rightful heir, and a magic system tied to the actual cost of using it. The series I am the proudest of so far.
Also on KU
Horizons Wake (techno-thriller trilogy, plus the in-progress Singularity sequel), World at War, World Reborn, The Darklands, The Nexus Chronicles, The Long Dark, Escape, and a two-book literary side project called Time. Plus stand-alones and the older first-novel-era stuff if you want to see where the writing started.

How this actually works
If you already have KU, open the Kindle app, search "Lincoln Cole," and tap "Read for free" on anything that catches you. Borrows count toward the algorithm the same way sales do, and KU pays me a royalty on page reads, so borrowing is just as good for me as buying. If you're between books anyway, this is the easiest version of supporting the work.
If you don't have KU, the 30-day Amazon trial covers everything above. Most people never claim it.
