There are two central characters, who contribute to the story, each sharing their opinions and feelings throughout the book. They are a boy and girl in their twenties who meet via an eBay auction and embark on a journey, so there is a will-they won't-they aspect throughout the book.
The plot has much hilarity and some personal issues and isn't crammed with gratuitous sex, which makes a change.
Maybe the fact that the writer is male stands the book apart from the usual light-weight girlie-fiction that generally provides only a female take on novels. An interesting story-line, too, as the pair spend a few weeks travelling round South America with the Hidden Planet guide, meeting some ordinary people rather than kidnappers and drug barons.
They keep in touch with friends back in the UK whenever they find an internet café and discover that they are minor celebs, which builds towards the end of their trip becoming a little less free-and-easy as they try to keep under the media radar.
It's a great first book from author Mark Green and I'm looking forward to his next book.
