Free Kindle book today only!

I put together some photos of Hilbert with a simple rhyming story and published it on Kindle.  I don't know how to make it free all of the time, but Amazon allows me to pick up to five free promotion days every three months.  I'll try to make a version free most Wednesdays.  So, if you miss today, look for another Happy Hilbert Wednesday!  Hilbert's Happy Day (Bilingual English Espanol)!
