Mercy's trial /cSever Bronny.
(Book)

Grasping at a sliver of hope, a group of friends undertake a perilous quest last attempted thousands of years ago . . . a quest to summon dragons. A ruthless enemy has conquered Augum's kingdom. Sheltered beneath a protective dome, the Academy of Arcane Arts stands as the sole remaining stronghold. And Augum and his friends are about to abandon it. Little does he know escaping will be the easy part, for a harrowing adventure awaits. Along the way, he'll have to evade an enemy that always seems one step ahead-while dealing with an ally questioning his leadership. But his greatest challenge? Learning when to show mercy . . . and when to drive in the sword.
