yesterday I found an interesting site
(better say, the site found me, someone sent me a link)
I was able to post there my latest book "Becoming a STEM teacher: a crash course for people entering the profession".
Now, everyone can download for free a pdf file,or a mobi file for reading the book on Kindle, or epub file for an iphone or an ipad.
Here is a link.
But what I like the most is that everyone who likes the book can leave for me a small gift :)
Hope you will like the book!
