Good permaculture book for in-laws living in dry areas (WY, NV)?

It's time to get Christmas presents for the in-laws.  I have some books I recommend for people in similar climates to my own but these folks live in the hills of Nevada and Wyoming (not pure desert but rocky and junipery).  Does anyone know of a permaculture book that comes from those areas or that would speak to these folks better?  Giving them a book with lots of pictures from Oregon may trigger a "that won't work here" response...

My favorite books for drylands are:

Rainwater Harvesting for Drylands and Beyond Volume 2 by Brad Lancaster

and

Growing Food in a Hotter, Drier Land by Gary Paul Nabhan

Mike, I second Tylers recommendations.
What part of Wyoming are they in? Permaculture is starting to catch on in Wyoming and they might have some places close by to visit?

Thanks Tyler and Miles!  I should have mentioned that they aren't interested in permaculture (yet) so I'm hoping this might get them on their way.  I often start people of with Practical Permaculture by Jessi Bloom.  I'll scan it again to see if it would be good for them but I suspect the photos will be too lush...

The WY relatives are in Lander.  Nearby sites would be great, both for them and for me to visit the next time we're out there...

I always liked Lander, kind of in a "banana belt" area if I remember correctly. You might ask them if they have seen any of the Wyoming farm to Fork you tubes. Seems like there were a couple of farms on there that were fairly close but I would have to watch them again for sure.
