Marketed as 'Jurassic Park for the Lost Generation' it must be said Fragment has no link with Lost other than it is set on a Pacific island (indeed one wonders why the 'Lost Generation' can't just watch/read Jurassic Park...). Anyhow, the newly (re)discovered island is a biosphere of fragment of a lost prehistoric continent that has evolved is a totally different way to the rest of the planet. This is explained in typical Michael Crichton pseudo-science babble by a group of scientists that tend to get eaten by various carnivores on the island (I would guess this book has already been optioned by Hollywood and it will make a great summer blockbuster).
Whilst Fragment isn't going to win the Booker Prize (even ignoring the fact it hasn't been nominated) this is a good little "airport novel" (indeed I read over half of it at Paris CDG and on the plane to Bristol), with lots of interesting monsters and some ideas for games. SF gamers looking for inhabitants of a death world (or just some new xenos) will get something out of this.
