J.C. Hutchins' 7th Son is a seat-of-your-pants near-future scifi thriller.
For some incredible old-style radio adventures, check out the Decoder Ring Theatre! Black Jack Justice is my favorite, by a nose over the Red Panda. (And you can get an audiobook of the Tales of the Red Panda, too)
And, of course, Mur Lafferty and Christiana Ellis are fantastic. I can't choose between Mur's Playing for Keeps and Heaven series, and Christiana's Nina Kimberly the Merciless is a must-listen.
