The author, Suzanne Collins, is the author of the hugely popular "Gregor the Overlander" series. This book is waaay beyong that.
The plot is, the main character lives in the future where there are 13 districts. Each district sends a boy and a girl in to compete in "The Hunger Games", a 2-week battle to the death. The last one standing is showered with gifts. The main character is chosen, and has many conflicts to deal with, including possible romance and friendships.
This book has a very strong storyline, but that's not the strong point. The best part is the incredibly strong characterization that happens in the story. Katniss, the main character and narrator, has very strong feelings and opinions. The whole book reads like a great action movie - no end to the action, no slowing done. Loved it!
