Ooooh, this is right up my alley!
Niv, Name of the Wind and the Wise Man's Fear are so great. The Doors of Stone is supposed to be this year, too.
The best series I have ever read is the Song of Ice and Fire - Game of Thrones and its sequels. They are incredible. Some of you might be a little young for them, still - but when you get out of high school, pick them up. Or now, if your parents won't object.
My favorite book ever? Such a hard question. I won't even try, I'll just give a list of honorable mentions:
GRR Martin's series ASOIAF.
Lord of the Rings, Tolkien.
The Dark, John McGahern.
Catcher in the Rye, JD Salinger.
At Swim-Two-Birds, Flann O'Brien.
The Eyes of God, John Marco.
Dragonlance Legends, Weis and Hickman.
Princess Bride, William Goldman.
The Once and Future King, TH White.
The Dark Half, Stephen King.
Tenth of December, George Saunders.
Picture of Dorian Gray, Oscar Wilde.
Macbeth and King Lear, William Shakespeare.
Everything by James Joyce and everything by Seamus Heaney.
Idk. That's off the top of my head, and I am sure I am missing things that deserve to be on there.
I'll give Harry Potter a mention, too.
Most recent books?
I read Gone Girl, Gillian Flynn, and I also read Dark Money, Jane Mayer. Both were great.
