Watch out! Finn faces more monsters than ever in Darkmouth: Chaos Descends, the third book in the tween fantasy series that Kirkus Reviews called, "Ghostbusters meets Percy Jackson as written by Terry Pratchett." Finn isnt even a full-fledged Legend Hunter yet, but he's already had to save the world twice. The Legends are planning their next attack and, of course, its up to Finn to stop them. Too bad hed rather be doing anything else.
