While working on the product info for the new "Best Brain Exercise" book,
I decided to update the page for the "Colossal Killer Sudoku" book.
(at https://www.amazon.com/gp/product/1517766028)
For some reason the book description was missing from the page, for example (!)
I also updated the cover image (darker background, different font, higher contrast)
I'm looking to add endorsements for this one too (similar to the one that's now on the BBE page,
i.e. "I love these puzzles, they keep my brain alert, which helps a lot when teaching math!", J. Bloemhof, high school math teacher),
so if anyone is up for this, let me know
