Charles Vrooman added a status update: To make my Kindle thrillers more available, I’ve dropped the price from $2.99 to just 99 cents. Even though these novels are more then 10 years old, their relevance for today is still important. Green Power: Domestic bioterrorist sabotage alternate energy source, causing an epidemic. The True Virus: Hamas bioterrorist hack into DNA component of CIA computer to create a live virus that causes an epidemic in Israel.
