The House Of Hades (heroes Of Olympus, The, Book Four)
The House Of Hades by Rick Riordan is impossible to be described in words. Rarely has a book ever left me speechless, which is why i suggest you read it to find out what i mean. However if you know nothing of the series read the Percy Jackson and the Olympins', then read The Heros of Olympus' series, and find out if you are truely at a lost for words too.
The Host (The Host, #1) Seriously, one of my favorite books. I don't know where this Stephenie Meyer was when Twilight was being written, but I probably would've liked Twilight a lot more if this Stephenie Meyer had written it as well :|
