Sanctuary - The Ramulas Chronicles, #2

THEIR ONLY HOPE IS TO DEFEAT BOTH THE LEGION AND AN ENEMY CLOSER TO HOME. With the help of the King's magician Shigar, Ramulas and Pip avoid capture and race to Sanctuary to find Oriel, where she is trapped within a mountain. A war with the legion is coming, and Oriel sends out a call across the kingdom for help, which is answered by thousands who come to Sanctuary. While the people train for the fight and dig into the mountain to free Oriel, Remus and his warlords weave magic to cross into this world to ravage everything.
But King Zachary, angry with his magician for joining Ramulas and his people worshipping the escaped prisoner, prepares his army to march as soon as his spies locate Ramulas.
