My Book Despair! about the ill-fated fourth voyage of Christopher Columbus is available at Amazon’s Kindle Bookstore. The price is $2.99 though it’s currently listed at $4.99 and I’m trying to get that corrected.
It is also available at Smashwords.com in eight different formats if you don’t own a Kindle.
Also available at Smashwords is my short story:
Sailing Alone To Isla for 99¢.
And the first volume of From Powder Monkey to Admiral that I heavily edited and rewrote. It’s also 99¢.
