This is the world of nano technology a young adult novel of twenty-first century warfare in the human ecosystem, a fight for control.  Michael Grant has begun a new series in the computer game world on a micro scale where the human body is the battle ground.  There are also conflicts on the macro level, the regular life.
Vincent is the greatest nano warrior alive.  Noah and Sadie are recruited into this world into a secret cell not knowing what they are getting into.  Trained for a war they have no idea existed and can barely grasp the technology because it is so new.  Sadie's father pioneered much of it to aid medicine in healing severe conditions such as cancer and to fix the aneurysm Sadie has in her brain.  However when others weaponize the new technology a dark conspiracy emerges.  It is just a group of teen hackers who call themselves BZRK who are trying to save world leaders.  It is victory or madness.  This is a suitable fiction read for science units on robotics, nano technology and computer science.

City of Bones by Cassandra Clare

This is book one of a series of fantasy books that makes a good follow up to the Twilight series.  Everything is in it...vampires, werewolves, the fair folk, angels, fallen angels or demons, the Nephilim or Shadowhunters as they are called along with ordinary humans. You are introduced to each creature and it's kind as the plot unfolds.  Nothing is as it seems.  The plot twists and turns with unexpected surprises.  It all begins with the Pandemonium Club in New York City where the main character Clary Fray just is not expecting to witness a murder.  Nor does she expect to see three teenagers covered in odd markings, one of whom is called Jace (very handsome).  These are the Shadowhunters, warriors dedicated to ridding planet Earth of demons while policing the werewolves and vampires.  Suddenly Clary's mother disappears and she is attacked.  How suddenly did she get the "sight"?  She is not supposed to be able to see in to the unseen world unless she is more than just human.  Questions abound that need answering as one thing leads to another.  If you like fantasy with a love triangle plus a mystery, it is suitable for older teens.

The Mortal Instruments: City of Bones

This sequel to Under a War-torn Sky by L. M. Elliott is a historical novel that will bring reality of what it was like in France after World War II to the reader.  Henry Forester, nineteen years old can not forget the horrors of the Gestapo, fighting battles against the Luftwaffe and a small boy named Pierre who saved him.

Home in Virginia nightmares wake him up and he decides to face his unresolved memories by going back to France to find and aid Pierre, if he can find him.  Pierre lost all of his family in the war.  Henry is unprepared for the aftermath of war that involves starvation, shattered cities, the return of concentration camp survivors and the internal strife among the various political groups.  The last chapter, Afterword, gives real history and newer findings about the aftermath of World War II making this novel a worth while addition to any unit on World War II.
