The first in Michael McGarrity's Kevin Kerney series,
Tularosa. is on sale in the US for $2.99, and discountable at Kobo. The Kerney books don't go on sale very often in the US, although they have been going on sale a bit more in the recent past. So if you want it, I'd grab it. (Although this one was briefly at $1.99 a couple of months ago, but I missed it. So if you really want to be patient, you could cross your fingers and wait...) I'm quite fond of this series, although I do have a bias towards books set in the American southwest, since a good chunk of my family is from there.
