A return to more like the form of Patient Zero in this latest outing for Joe Ledger & the DMS as opposed to King of Plagues & Dragon Factory. Fast pace, unrelenting action, wierd science, vile villains and goods guys sometimes just as scary. As other reviewers point out, you will get a lot more out of this book if you have read the others in the series, as elements of the plot carry or remain unresolved, and the world view, with science rationalised supernatural elements is the same.
Joe Ledger still retains his black sense of humour along with his multiple personalities & devotion to martial arts. The relaionship with Ghost, his canine companion, gives a centre to a charactor that has to endure a lot (again). Plot elements that remain consistent are the deaths of characters we love or hate from previous books, charecter development of the 'regulars' and enough uncertainty to leave you wanting more along with the resolution.
You will enjoy this book if you liked the others in the series & enjoy fast paced remotely technically plausble imaginative thrillers where the world is in danger agaist overwhelming odds.
