The plot and pace are good but the writing itself is generally poor.
Dialogue is particularly cringeworthy with British characters getting the shortest shrift - the author seeming to have drawn his inspiration from Dick Van Dyke in Mary Poppins.
Biggest crime of all though is that despite being given a clue almost as obvious as a cross on a map, the supposedly brilliant protaganists stumble around scratching their heads until mere moments before the terrorists launch their final attack. For the climax to be effective it needed a much more subtle build up than it got.
Summary: Equal parts entertaining and disappointing. Not a patch on World War Z by Brooks
Genius, the indepth science behind what goes on in this book is reminiscent of the Great Crichton, the pace is fast, action packed and squeezes 72 hours of fast paced, non stop action into just 3 hours of reading, to say i couldn't put this down is an understatement. If you enjoyed Brook's World War Z then this is a must read for you.
