Zack, the son of a palaeontology professor, goes to Utah with his girlfriend following the discovery there of a hatched baby Raptor. The expedition forms the basis of an action-packed adventure, which is compelling enough to stand up to the special effects of the silver screen. There's plenty of blood and poisonous green dinosaur spittle, but it's not gratuitous.
Those wanting a less bloodcurdling monster story should be directed to Spacebaby and the Mega-Volt Monster (Collins pound;9.99) by Henrietta Branford, her fabulously funny and chaotic follow-up to Spacebaby. This fast-paced adventure, moving from Portland Bill to Loch Ness, reminds us what a versatile and inventive talent has been lost since her death earlier this year.
