It's always good to discover a new name in the thriller field and if Jack Henderson keeps to the very high standard of this debut novel, he's going to have a long and successful career.
The characters are well-drawn and engaging - the author has avoided the common trap of making the good guys Hollywood-perfect and the bad guys cartoon villains - and the plot and plot twists keep you hooked : you'll find yourself meaning to stop at a chapter end, but somehow just reading a few more pages, then a few more...
The author obviously knows his stuff with regard to the technology side, but at no time is the reader baffled with science - the human element remains the mainstay, and the tension keeps ratcheting up.
In all, a very fresh approach to the thriller genre, enjoyable and satisfying, and I look forward to the next one from Mr. Henderson.
