First impressions are not good but the cover is very misleading, it gives the impression of a cheap and trashy sci-fi outing, when in fact it is an entertaining read, with a well-developed plot. Whilst the plot is good, the book is severely let down by it's simplistic, often child-like, writing style, which means that it reads more like a Young Adult book rather than the adult fiction it is. Hopefully this will be improved in the rest of the series. The simplistic writing style is countered by the brilliant pacing of the novel, particularly near the start, which makes this a sure page-turner.
