Hailed as the new Twilight (even though it was first Published in 2008) The Hunger Games, by Suzanne Collins, is the story of Katniss Everdeen, a 17-year-old girl who volunteers to take her younger sister's place as 'tribute' in the barbaric (and televised) fight to the death that is The Hunger Games (and obviously the name of the book).
The story takes place in a post-apocalyptic world called Panem that is divided into 12 subservient districts surrounding the controlling power of the Capitol.
While she is fighting to stay alive, she also has to figure out her feelings about Peeta, the male tribute from her district, as well as discovering which tributes can become trusted allies and who is just there for the blood sport.
Now, don't let this talk of post-apocalyptic worlds and fighting to the death turn you off reading this book if you are generally more into romantic stories, because the Hunger Games has a lot of heart. Between the love for her sister and a possible love triangle for Katniss, Suzanne Collins makes you feel for her heroine at every turn. (But if you're a Twilight fan who needs more encouragement, then there is an endorsement from Stephenie Meyer on the cover.)
The book is the first in a trilogy (Followed by Catching Fire and Mockingjay), so if you're only reading it now, you'll probably kinda have a hunch that she makes it out alive right from the start. But that doesn't stop you from being completely involved in the story and her struggles.
I would recommend buying all three books at once because it is near impossible to not be hooked and the idea of having to wait even a day would be unbearable. This is a fantastic book which can be equally as enjoyable to guys and girls (I gave it to my male housemate and he finished it in like two days!), so buy it, enjoy it and then share the love.
If you're not a reader then the big screen adaption, starring Jennifer Lawrence as Katniss, is coming to theatres in March and also features cameos from Woody Harrelson, Elizabeth Banks, Lenny Kravitz and home-town hottie (not to mention Miley Cyrus's BF), Liam Hemsworth.
