Lennon Carter’s life is falling apart. Then she gets a mysterious phone call inviting her to take the entrance exam for Drayton College, a school of magic hidden in a secret pocket of Savannah.

That is, until a mishap with a forbidden spell binds Leo to obey the commands of his longtime rival, Sebastian Grimm. Grimm is Leo’s complete opposite—respected, exceptionally talented, and absolutely insufferable.
