After the debacle that is Seven Ancient Wonders, Hell Island is a timely reminder that Matt Reilly can, when firing on all cylinders, be one of the best writers of action around.
The plot may be in no way original, the characterisation almost non-existent and both reality and the laws of physics may be stretched to breaking point (all of which you expect with Reilly's work) but any deficiencies are made up for with blistering action that crams 90% of the book's truncated length.
Digestable in an hour if you're a quick reader, this is the literary equivalent watching an episode of TV's 24 or Alias...pulpy, disposable, unbelivable but damn enjoyable and not too time consuming.
So, rather than pick up a magazine for that train journey try a shot of Hell Island instead. It will not cost you much more and it will hold your attention...
