First they could hear the Roar.  Now they can hear the Whisper.  Emma Clayton finishes the story of telepathic twins Mika and Ellie in The Whisper (Scholastic 2012).  Now that Mika and Ellie are reunited, their mission turns ever more dangerous.  They have discovered that Mal Gorman and the Northern Government have raised an army of children to take back the the lands on the other side of the Wall.  Mika and Ellie must pretend to go along while planning to lead the other mutants and the sleeping army in a rebellion.

I was glad to learn that Clayton had written a sequel to The Roar.  The ending of it left me wanting more, and The Whisper delivers.  Just like the first novel, the action is nonstop.  Mika and Ellie may have found each other, but their troubles have just multiplied.  It will take all of their skill and mutant abilities to keep war from breaking out.  Not only do they have to defeat the Northern Government, but they also have to convince those in power outside the wall to share its riches and bounty.  Even more difficult, they have to keep their parents from demanding what is justly theirs and exacting vengeance for what they have been denied.  In the end, it all comes down to timing.  If they succeed, they can lead the way into a new future with hope for everyone.  If they fail, the resulting war may lead to utter destruction of the world.
