Book suggestions please

I've been enjoying reading some dystopian fiction recently, just finished reading the Margaret Attwood trilogy, oryx and the crake which I loved! Love the rest of her work as well. Have enjoyed hunger games. Read the maze runner which was quite good but other 2 in series not great. Liked unwound though not thrilled with the ending of the last book and not really a patch on the Margaret Attwood. Any suggestions for a good dystopian novel or series of novels, can't seem to find another good read, thanks
