Sheba — Will B. Aarons

Sam Durell is sent into the wilds of dangerous Ethiopia to find out about a deadly blast in the desert. He is faced with assassins, a rogue CIA ex-SEAL that he cannot trust, a couple of tough and determined ladies that can hold there own, a sinister force behind the plot bent of wholesale destruction, a ruthless Corsican mercenary and a plethora of paid killers, spies and tribesmen caught in the middle. Lots of narrow escapes, torture sessions, daring flights, fair amount of gunbattles, cave-ins and grenades being tossed into hotel rooms
