Book 83: Super Human by Michael Carroll

In the near future, there are super heroes and super villains.  One group is trying to bring back a serious villain who died several thousand years ago.  They create a virus that wipes takes down any adults.  It's left up to a few teenage heroes (powered and not) to defeat the bad guys and save the adults.

Quick YA book.  My 10 year old actually read this at the same time.  He really enjoyed it.  I did too, but it's definitely aimed at that young reader demo.
