After her mother dies in an accident, sixteen-year-old Bree Matthews wants to escape. A residential programme for bright high-schoolers seems like the perfect opportunity - until she witnesses a magical attack her very first night on campus

A flying demon feeding on human energies.
A secret society of so-called "Legendborn" that hunt the creatures down.
A mysterious mage who calls himself a "Merlin" and who attempts - and fails - to wipe Bree's memory of everything she saw.

The mage's failure unlocks Bree's own unique magic and a buried memory about her mother. Now Bree will do whatever it takes to discover the truth, even infiltrate the Legendborn. But when the Legendborn reveal themselves as the descendants of King Arthur's knights and foretell a magical war, Bree must decide how far she'll go for the truth. Should she use her magic to take the society down - or join the fight?
