"A top-notch, police procedural suspense set in the beauty of Wisconsin’s Northwoods. Creatively written with thrilling twists you won’t see coming!"

Valerie Biel | Author of the award-winning mystery, Beyond the Cemetery Gate. 

"Jeff Nania’s Northern Lakes Mysteries are reminiscent of the flavor of Michael Perry, and the newest, River Gold, offers far more than a straight-line police procedural."

Praise for Northern Lakes Mysteries

  • Tim Eisele | Freelance Outdoor Writer and Photographer

    The author's knowledge of Wisconsin's Northwoods, fishing, and law enforcement techniques, brought me hook, line and sinker into the story, and I thoroughly enjoyed reading the books.

  • Laurie Buchanan | Author of the Sean McPherson Novels

    What do you get when you mix together a good guy who's weighed down with heavy emotional baggage, a bad guy you love to hate, and a dash of romance? A page-turning read!

  • Doug Moe | Journalist and Author

    Jeff’s great appreciation for the natural world, both its beauty and danger, shines through all the books, but [Musky Run] offers a thrilling Northwoods race and a page-turning finale that will prove either the swansong or salvation of his memorable protagonist, John Cabrelli.
