Propulsive And Explosive. This is one of those books where every challenge only leads to a more difficult challenge - and the challenges don't start easy for our hardened and capable yet flawed hero. As the stakes rise ever higher, attacking everyone Koa Kane loves, can he save... anyone? Even himself? Well, this is an action book seemingly in the middle of an already successful series. So he's going to save people, that's what heroes do in these types of books. But McCaw grounds these books in a fair amount of realism as well, and therefore... well, some may die. Or may not. You'll have to read the tale to see what happens. :D But that ending, setting up an explosive confrontation with a foe Kane thought conclusively dealt with... yeeah... I'm absolutely looking forward to seeing where McCaw takes this series next. Very much recommended.
