Apologies in advance if I'm violating any rules -- I just wanted to thank everybody here for the information they share (and for putting up with my occasional enthusiasms) by offering a freebie copy of my new self-published eBook on Decade Volcanoes through Google Play by entering this code: PZ0MCLKVWW0M8 .

It's only good through the 12th and limited to 250 copies, but my blog readers are included, too. So if this code is used up on or before the 12th, please let me know and I can email or PM you a one-time special code.

(Couldn't figure out how to do this with banner ads, but I WILL use those when my author site goes up later this year.)
