Something about that cover makes me feel like an angry Scotsman. 'nnnngry!
Maybe just too busy and the red stripes are waving at me? Maybe because the protagonist is a dude and that's (hopefully) not him on the cover? Maybe the whole "Artemis Files: 1" is a bit arrogant (How many multiple-book series announce themselves that blatantly? If it is good we clamor for follow-up).
Description feels too jingly. Overly melodramatic, cliche, and pop culture ("What stays in..." Really? Tell him to fire his editor, if he used one).
Did you read this book and now recommend it as a fellow reader of SF, not just as the author's friend? Did you like most the characters, the twisty plot, the novel SF ideas, the strange aliens, or... what makes this one special?
