Book was released earlier this summer: https://www.amazon.com/Straight-Talk-Armed-Defense-Experts/dp/1440247544
I know I've not posted here in awhile, but thought some folks might be interested. I don't make any additional royalties based on number of books sold or the like, I've already been paid what I'm going to get out of the project. I say that just so you know I've got no financial interest in recommending it. I do think it's a worth the read. Combine it with Massad's "In the Gravest Extreme", Gavin di Becker's "The Gift of Fear", and Rory Miller's "Conflict Communication" and "Facing Violence" and you've got a pretty decent foundation to start being serious about self defense. You'll get a good primer on avoidance, deescalation, unarmed and armed self defense, and dealing with the aftermath.
Oh, and I've also got an ongoing writing gig with Lucky Gunner: http://www.luckygunner.com/lounge/author/spencerblue/ and am still running a few training classes a year through Bright Firearms Training. We've got students from as far away as Washington DC for the fall class coming up next month.
