Solid, cute, sometimes clever and funny, tale about a geeky Viking kid, Hiccup Horrendous Haddock III, who's trying to train a selfish, lazy, runt dragon (whom Hiccup accurately names Toothless).
Worthwhile read; don't bother owning it, unless you have a small child who absolutely loves dragons and/or Vikings. (The resulting CGI movie, sans the 3-D money grab, is worth owning -- its reworked/streamlined story structure, and action- and humor-packed plot pacing improve on Cowell's humorous but comparatively static-paced book.)
This series includes other Hiccup Horrendous Haddock III-centered books, namely: How To Be A Pirate, How To Speak Dragonese and How To Cheat A Dragon's Curse.
The movie version was released stateside on March 26, 2010. Dean DeBlois and Chris Sanders co-directed and co-scripted the CGI film.
