This is the second in the series by Adrian McKinty, and it is a true, high octane thriller, like Dead I Well May Be, which precedes it in the Dead Trilogy. I didn't get the galley, and have never been able to get one by this author, but he's good enough to send me rooting through the virtual stacks at Seattle Bibliocommons. Once more, it's Gerard Doyle that performs the audio version, and oh, he is excellent!
In the first of the series, Michael Forsyth, our protagonist, is set up to land in a Mexican prison forever, and he escapes because he is BAD. Here we find him in a witness protection program in the US, and his FBI handler comes a-calling. They need him to infiltrate an IRA support organization, terrorists all, named The Sons of Cuchulainn. Of course he doesn't want to, but they play their largest, ugliest card: he is still wanted in Mexico, and they'll extradite him if he doesn't take the job. And so he does.
This book is riveting. My spouse, who still works from home for a living, generally wants me to turn my audio book off or go to earbuds when he comes down to the kitchen for lunch, but he's decided he wants me to leave Adrian McKinty's books on. This is the only author to win this distinction in over four years.
My only word of caution is that unless you are an unusually phlegmatic, unexcitable type, don't read this book at bedtime. You may also not enjoy some passages while eating; it's violent as heck, though not gratuitously so.
I recommend it wholeheartedly, but I do recommend reading the trilogy in order, so don't start here.
