This First Light of Dawn by Jefferson Glass

“Like a bracing wind of morning, The First Light of Dawn slaps you awake and widens your eyes– Jefferson Glass’ debut of the Conor Armenta mystery series is truly something to look forward to any time of day.”

Craig Johnson, New York Times bestselling author of the Longmire Series

“Jefferson Glass has penned an engaging first novel. The First Light of Dawn is Sheriff Conor Armenta’s debut, and beguiling one it is. Glass has a talent for crisp and well-rounded characters. When does the next Armenta novel release?” 

W. Michael Gear, New York Times bestselling author of Dissolution

“The First Light of Dawn is an engaging period mystery set in 1930s Clark County, Nevada—before Las Vegas became Las Vegas—and filled with an interesting collection of colorful characters headed by Sheriff Conor Armenta.  The novel offers enough red herrings to intrigue mystery aficionados and enough plausible plot twists to keep the reader turning pages.”

Preston Lewis is the Spur Award-winning author of more than 40 western, juvenile and historical novels as well as numerous articles and short stories. He is best known for his comic westerns, including the well-received Memoirs of H.H. Lomax series

“There’s a new star on the horizon in contemporary Western mysteries and his name is Jefferson Glass. Glass’s Conor Armenta novel is an action-packed thriller with memorable characters that rival any of those featured in the works of Johnson, Box or Hillerman. Exceptional writing and unforgettable plot twists.” 

Chris Enss, New York Times Bestselling Author and Chairman of the Will Rogers Medallion Awards.

5.0 out of 5 stars Mystery in the Las Vegas Desert

Engaging from the start and an intricately woven mystery set in Depression-era Las Vegas area. Descriptions throughout were so logically and believably detailed one can feel like they are in the room or way out in the desert on a rock watching everything unfold. The author’s style is unique and may have been helped by his non-fiction writing as a discipline. His first fictional story was a pleasure and I look forward to reading the next volume when it comes out.

5.0 out of 5 stars Top notch work from an award-winning author

Reviewed in the United States on December 1, 2023

Jefferson Glass may be best known, at least to me, as a non-fiction historical author who has won awards for his work, including a Western Writers of America Spur Award, and a Will Rogers Medallion Award.

Going into this first foray into Glass’ fiction, I was hesitant because it’s been my experience that non-fiction authors don’t always make the best fiction authors. Boy howdy was that hesitation for nothing. The First Light of Dawn is as good a first fiction novel as I’ve ever read (and some far bigger names than me agree).

I was at turns delighted and intrigued with the writing style and the way the story flows. And I’ll admit, he caught me off guard at one point, in a surprisingly good way. This first instalment of Sheriff Conor Armenta’s series is a worthy read, and I am anxiously and eagerly awaiting the second one already. This one reads really, really fast, so hold on to your hat and get ready to be swept away to Vegas in the early part of the Twentieth Century. You won’t be disappointed.
