After I read the 1st book in the series I found that I "had" to read the others because I was so invested in Katniss. Here's a young girl who from the moment you meet her she is a pawn in someone else's game. Living in district 12 she becomes a tribute for the Hunger Games where children fight to the death for the amusement of the Capital. During the games she struggles to determine other people's motives as well as her own. Does her fellow tribute Peeta really love her or is this really just a strategy to survive the games?
As you follow her throughout the three books you realize that Katniss is always being used for someone else's ulterior motives and then you start to see her own strategy come into play.
I loved the series and found the characters interesting and often sad. Each of the characters changes, grows, and are often distroyed emotionally but somehow come thru it. Not unchanged, but they survive.
Well worth the read
