A limited number of free copies of Einstein's Beach House and Miracles and Conundrums of the Secondary Planets remain available for anyone willing to write an Amazon review and/or promote through social media (as well as for college students, public libraries and other nonprofit literary institutions) Or if you can make another compelling case for a free book, I'm very open to any sincere requests.
If you are interested, please send a request with a postal address (including zipcode) to jacobmappel@gmail.com
Please feel free to share this offer with friends and on social media.
