Apparently the next-in-series is due out soon according to the author's bio-blurb (not listed for pre-order yet in Canada/UK, but maybe already in his native land where HarperCollins Australia apparently publishes these first), hence this introductory freebie.

Description
Paradise turns to terror when pirates hijack a luxury yacht ...
Paradise turns to terror when half-starved, AK47 toting gunmen, led by a soldier of fortune called Drake, board Peter and Victoria Holt-Bennett's luxury catamaran off the coast of Guinea. Terrorised and violated, the hostages must attempt to raise five million dollars to save themselves, and their four year old child.
While their lives hang in the balance, a team of crack 2CG operatives, led by Marika Hartmann, launch a do or die mission to save them. But Drake is more than he seems, and the stakes are higher than anyone could have imagined. Battling against modern weapons coupled with malicious stone-age beliefs, Marika will match wits with a man who appears to anticipate her every step.
