I've just released a new puzzle book called
Chihuahua Puzzles Galore:

I've crammed 400 9-letter puzzles into the book. Rather than have a volume of more than 500 pages, I've put four puzzles to the page. As a consequence, there's no lined space for writing answers, so the reader will have to provide their own paper for this.

The book's web page is
here, with links to its Amazon pages.
