This is the first book in Steve Cole's excellent 'Astrosaur' excellent series, which now totals 19 books. This book is the UK 2010 edition and has been reprinted with new cover artwork, but otherwise it's identical to the old cover version. There's still the nice book illustrations every few pages, and the 'free cards' in the front with pictures of the crew and so on that the kids can remove and collect. The books are aimed at 7 to 9 year olds, and once hooked at 9 kids will probably read them until about 12.
My son is dyslexic and isn't very good at reading, so I read these Astrosaurs books to him at bedtime. He really enjoyed them and so we bought all of the Astrosaurs series to encourage him to like books as much as his Playstation, TV and DVD's [didn't work but the only book he ever read cover to cover himself was an Astrosaurs one]. We are Dr Who, StarWars, Dinotopia, and Jimmy Neutron fans and you get the boys top favourite (dinosaurs) thrown in as well. The only problem with them is that Steve Cole can't write them quick enough - and the SciFi content of the stories is improving with each new book. To quote Amanda Craig, writing in the Times, these books are "the kind of inspired, hysterically silly fantasy that boys adore".
The series follows the space adventures of a troupe of vegetarian dinosaurs (they escaped the meteor hit 50 million years ago by leaving Earth in spaceships). Captain Teggs and his crew, Gypsy, Arx and Iggy are no ordinary dinosaurs - they are Astrosaurs! They fly through space in the Dinosaur Space Service starship, the DSS Sauropod, keeping the peace in the vegetarian sector of the Jurassic Quadrant. They also patrol the neutral VegMeat zone to defend against the inhabitants of the notorious Carnivore Sector. Plus they are explorers, who boldly go where no fern chewing reptile has boldly gone before.
In this 'Riddle of the Raptors' book newly promoted Teggs and his crew are transporting the sector's top vegetarian athletes to the Great Dinosaur Games at Planet Olympus. Suddenly a Raptor Deathship appears and attacks the DSS Sauropod, and a Raptor boarding party kidnapps two of the best athletes. But there's more to the Raptors' plot than meets the eye, so can Captain Teggs solve their rascally riddle in time? Like the rest of the series, the book it is suitably tense in places for little ones, but never that scary for under tens.
The books are best read in order. My son says "Like the other books it was cool, I liked the characters and the pictures (the reading books are filled many good line drawing illustrations). I also liked the cut-out cards at the front". I would think the books would suit any pre-teen boy older than four, who appreciates space travel (probably up to age 12). I also enjoyed reading them out loud. There are surprisingly few good books aimed squarely at young boys about, so highly recommended. Also look out for the newer 'Astrosaurs Acadamy' series [Teggs et al as youngsters in Star Fleet School], and the time travelling 'Cows in Action [CIA]' series. As a preteen my son also liked 'The tentacled terror' plus the 'Horrid Henry', 'Seriously silly stories', the US 'Captain Underpants' series of books, however it's these Astrosaurs books he holds in the highest affection.
