Inheritance Cycle, yes man, I know that feel.

My personal favorite is The wheel of time series. I feel empty and sad after every book...

Haven't read any of those.

I still haven't gotten around to read the last book. same with the GONE series

GONE?

It's a bok series i read. a town gets locked in some supernarural dome and every person over 15 disappears. at the same time thw animals mutate and the kids get weird powers. the series is about breaking out of the dome, surviving and uncovering the mystery.

i would recommend it strongly, but only if you aren't afraid of a rather dark story line.

The awkward 1 minute after finishing a book where you don't know what you want to do?
