Young Adult Dystopian Fiction

It is the  NUMBER GREATER THAN 31 of  COMBINE TWO MONTHS, time for the  COLOR PLURAL to join their  ANIMAL GROUP NAME. I hear the  ELECTED POSITION, a  DIFFERENT COLOR, call from Room  BINGO SQUARE.

I've been waiting for this moment as long as I can remember, but, as my brother  ANOTHER BRAND NAME says, "Nothing prepares you for  HOLIDAY NOBODY CELEBRATES."
