I have to say, that if you can't read a book without analyzing and reading to actively criticize, then you will certainly find loads of things to criticize about this book - the gore, the incessantly repeated phrases often within a couple of pages of each other, the cliche's and the ways that the main characters get out of situations. But, I read for pure enjoyment, nothing else, and if like me you read for enjoyment, love fantasy, science-fiction, and pure fun, then you will love this book.
For anyone who is slightly confused - yes, this book has the flaws that I have mentioned, and many other people mention them also, but I either don't see them as "flaws" or they barely influenced my enjoyment for more than a few milliseconds at a time - hence the five star rating.
Deathstalker is a book centered around a young man named Owen Deathstalker, an amateur historian, outlawed with a price on his head by the Empress (also known as the Iron Bitch). The novel follows his adventures to several enigmatic planets with his companions - Hazel D'Ark, ex-clone-legger and pirate; Ruby Journey, the bounty hunter; Jack Random, the professional rebel; Tobias Moon, the cyborg; Ozymandius, the AI (artificial intelligence); and Giles, the 900 year old original Deathstalker, founder of his clan.
The book also follows the movements of the Empress's court and the nobility, with intriguing and diverting characters here also - Finlay Campbell, the fop and dandy with a deadly secret; Evangeline Shrek, lover to Finlay and, as seems to be common among the nobility, with dark secrets of her own; Kit Summerisle, Kid Death, the Smiling Killer; David Deathstalker, cousin to Owen who became head of the Family upon Owen's outlawing. And perhaps my favorite character (in terms of disposition, not character, mind you); Valentine Wolfe. Valentine is an amazing character - a "professional" drug user, with cunning fighting skills and intelligence hidden behind the everyday mask of his scarlet mouth and mascaraed eyes. Despite his (to be frank) oddness, and (not so much in this book but certainly later on in the series) his increasingly unpleasant or downright evil actions, you cannot help but love this character, with his unique attitude and dialogue - a marvelous character to read.
And lastly, this book follows Captain Silence of the Darkwind, and later the Dauntless, and his comrades Security Office Stelmach and Investigator Frost, in his attempts to do his duty and follow orders from the Iron Bitch that he often has no taste for.
I think perhaps, aside from the dialogue (which I shall get to later), my favorite thing about this book and the later books in the series (which have their own charms) is that Simon R. Green shows us without a doubt that there are good people on both sides of a war. People whose differing beliefs prevent them from ever being able to agree or work together or even like each other - but because of the different points of view we are given, people on both sides are wonderful and like-able, or if not that then at least enjoyable characters nonetheless.
The dialogue, though as mentioned containing many cliches and barely disguised repeated phrasing, is consistently light and amusing, with friendly (and sometimes not so friendly) banter, jokes, and overall, a unique tone that Simon R. Green has throughout Deathstalker. This tone is not always "funny" as such, but it does certainly have a light touch and vague air of amusement to it at all times - except when there are heads exploding and the like. But the overall tone of the dialogue and descriptions, which is hard to explain unless you have read the book, prevents you from taking things like that too seriously - but just seriously enough.
Perhaps one of my favorite sequences where this banter and amusement is brought in is the sequence where Owen and Hazel go to find a name from a clerk, who subsequently goes on a rant about being "up to his lower lip in paperwork and sinking fast." He is certainly unhappy with his job - "the lunch break's a joke, there's only one toilet, and the pay's rotten. I'd quit if it wasn't for the pension. And the constant chances to screw up peoples lives... it's either this or planting explosives, and explosives are expensive." :D
Lastly, I should like to mention that I first stumbled across these books when my dad gave me the audio-books by Defiance audio for Deathstalker, Deathstalker Rebellion and Deathstalker War. The later books were done on audio with the same voice-actors, but by a company called Graphic Audio. I can justifiably say that the audio-books of Deathstalker are by far the best I've ever encountered. There is one amazing narrator, who does some of the voices along with the main descriptions, and he is accompanied by three or four other voice-actors - two men and two woman, I think. And these voice-actors also have wonderful variety and seem to me very talented. On top of this, the books have special effects (like making the voices echo slightly when said characters are, for example, in tunnels), sound effects (like the sounds of rushing water, sword fighting or energy guns firing), and also various fitting pieces of music that play along at suitable moments. The audio-books are quite expensive, but I would highly recommend them.
I have both the paperbacks and audio-books - for reasons mentioned above, the audio-books have their own charm, but the paperbacks do have things that the audio-books left out, and make the story feel less interrupted. Plus, they're far more fun to have on your bookshelf. :D
Overall, a wonderful, fun book that definitely has it's many flaws, but none of which ever bothered me in the slightest.
