This is a first printing of Book of Sting #2: Zaitech Sting by Mike McQuay writing as Jack Arnett, published in 1990 by Bantam Books.

From the publisher:

William Justice fights mean in the never-ending battle of right and wrong.  Ex-CIA commando turned free-lance mercenary.  Justice leads his hand-picked team to the hottest spots across the globe - but only if the cause is just.  Statesman, soldier, defender, killer, Justice protects only those who meet his own exacting code of honor.  He welcomes these dedicated warriors to his tropical island base, where he molds them into the ultimate weapon... aimed at changing the face of the world.

Justice angered Castro by offering asylum to desperate Cuban refugees.  But Castro's wrath is the least of his problems.  Another of Haven Island's fugitives is the mysterious Chika Stark, a beautiful woman with a dangerous secret - a secret so volatile both the CIA and the Japanese are willing to kill her to claim it.  Now the two superpowers are putting pressure on Justice to give up on the girl, or see Haven Island destroyed.  Instead the free-lance mercenary flatly refuses their ultimatum and launches a brutal counterattack of his own - one that could push him and his tiny island republic to the brink of disaster.  For William Justice has declared war on America!
