Tristan Montague has had his ability to cast magic broken. When his confrontation with Edith and Verity leave him unable to access his magic, he must seek out another technique to regain his access. He must learn the Restoring Palm. Now, together with Simon and the help of a dark mage, they must seek out someone who knows the technique and is willing to teach it to Tristan. They must find the Caretaker. Together they must evade Verity, who believes Tristan and Simon are going dark. To Verity, the only solution to darkness is erasure and elimination—a solution they intend to unleash before Tristan can restore his magic.
