Kronnus 13 by James Sharkey
FLY OR DIE.
A fatal virus that kills children when they turn thirteen has swept the globe. A distant planet holds the cure, but few children are selected to travel. Teenagers fly or die. Death or Kronnus 13.
Zak Connors received his acceptance letter the day after his thirteenth birthday party.
On arriving on the planet, he discovers he has special gifts and uses them to uncover the secrets of his mysterious new world, Kronnus 13.
