Amazon is offering several Bob Mayer books for free in the Kindle editions. If you don't have a Kindle, they have various apps for phones and PCs that you can read them on.
His stuff is pretty spotty - ranging from really good to not all that great. I have several of his books I got for free and some I had to pay for.
Just go to Amazon.com and search on Bob Mayer. The ones that are free will show up with a price of zero.
Here is a good one that is free right now.
I reviewed it and gave it a 4. I had to pay for it when I got it. But it was worth paying for. Some of his stuff is kind of out there. Like telepathic dog out there (that was in one of his books that I read).
I don't know if this is appropriate to post somewhere else here. I have to go to work, so if it is appropriate to move the post, maybe some one could do so while I am at work and have no access to "weapons" sites.
