Get your copy of The Persian Gamble
And if you haven't read it, I highly recommend you get the new paperback edition of Joel's prior book, The Kremlin Conspiracy, which will give you a lot of the back story for The Persian Gamble. (But The Persian Gamble is utterly enjoyable as a stand-alone.) Here's the link for The Kremlin Conspiracy: https://www.amazon.com/Kremlin-Conspiracy-Joel-C-Rosenberg/dp/1496406214
