Here are two of my early designs for the book cover before Cynthia came up with a more endearing one -- as seen on the main page.

 

 

This design features a cyberpunk version of the sun taken from the Philippine flag. I discarded it because I found it too simple and ordinary.

This cover simply shows a coin. Thailand and Singapore would have united and taken over the rest of Southeast Asia resulting to a currency called The Malayan Peso. The coin carries an image of a popular Pinoy celebrity.
