If you're into rushed, disappointing endings, then sure, read the Hunger Games trilogy.
Obligatory mention goes to the Song of Ice and Fire series because it's just THAT good.
Would also recommend "The Book Thief", which I need to re-read now, and also "His Dark Materials" trilogy (Philip Pullman) for some easy, but interesting reading.
Also, Ayn Rand's "Atlas Shrugged" is a good, thought provoking tome.
Others include:
The Curious Incident of the Dog in the Night time
Cloud Atlas
Shades of Grey (Not the porny "50 Shades of Grey" one) is one my boyfriend says to read. It sounds pretty interesting.
Anything by Terry Pratchett, if you've got an off-kilter sense of humour.
