He's rescued by the supernaturalists: Stefan, Mona and Ditto. They have one goal: to destroy these blue creatures they call parasites. Not everyone can see them, but some people, like Stefan, Mona and Ditto, are spotters. The supernaturalists know the parasites are always around when someone dies. They seem attracted to pain and the supernatualists believe they steal a person's life force. Since Cosmo is a spotter, Stefan allows him to join their group as they go up against the parasites. Eventually the group discovers that their activities have gained the notice of the giant Myishi Corporation and they are forced into a partnership.
I was instantly drawn into the fast pace of the story and the quirky characters. This is a young adult book (I would suggest preteen and older) so the plot is not overly complicated, but there is enough to keep adults interested as well. There's a little bit of intrigue when Cosmo discovers that not all the supernaturalists have been completely honest about their pasts. And just a bit of a love interest. For the sci-fi minded, Colfer provides plenty of interesting gadgets, including a weapon that shrink-wraps its victims, who then must be dipped in a vat of acid to be set free.
My Recommendation
The Supernaturalists by Eoin Colfer is a highly recommended sci-fi title for young adults. I enjoyed Colfer's style and wit. I was also impressed with Colfer's ability to create convincing characters. Often, I found myself rooting for the supernaturalists and feeling their disappointments. With the open ended nature of the ending, I can only assume a sequel is somewhere in the future, one I would be more than willing to read.
