Google has an easier way to do eBook promotions now, but that’s not the secret. This is: between today and January 12th, 250 blog readers (and folks at Talkweather.com, if I can do it) can download my new eBook on Decade Volcanoes for free at Google Play with this code: PZ0MCLKVWW0M8 .

Thanks, Google! Even more, thanks to everybody here for your interest and support!

If you try this on or before the 12th and this code has already been used up, please let me know and I’ll email you a one-use special code.
