The Shield Breaker

Fifteen years ago, magic destroyed the world. 

Cait Verlyn is one of a handful of survivors who make their home under the Shield; a protective spell cast by their leader, a powerful wizard named Vitoria. Cait dreams of leaving the Shield to explore the ruins and rebuild civilization, but it’s impossible without magic and she is forbidden to learn. 

Then she meets a stranger - a wizard from outside the Shield - who offers to teach her magic, but only if Cait will help the stranger overthrow Vitoria and liberate the enclave. The war of wizards that brought the world crumbling down is not over, and Cait's home under the Shield is the new battleground. 

Magic offers salvation, but as the apocalypse has proven, it always comes at a terrible cost…
