Wyvern's Destiny

Astri and her close friends are forced to hide in the city. They're waiting for an opportunity to strike back at the dark mage who took over Rivenna by force—the same mage who's been hunting her since she was eleven years old. 
When they leave the old mill to free her dear friend Emilia, people begin to spread terrible rumours. Apparently, Ruscal's planning to publicly execute his own brother. 
It's a race against time and Astri knows that she can't let Jorgen die. Will Astri save Jorgen and her beloved City of Rivenna or will Ruscal triumph once again?
