After twenty-seven years in the trade, Kaniev the Source-Fixer has suddenly lost his ability to repair magical Sources. He decides it's time to go home and take up fishing, but first, one more repair job lies ahead of him - Source Chaitrasse is experiencing problems. Kaniev's depleted finances and self-confidence demand that this time, he get the job done right.
Fransisa always thought she would be the next High Priestess at Source Chaitrasse, but now her career has come to a dead end. She's struggling to hold on to her place at Chaitrasse when a wandering tradesman appears, claiming that the Source has a problem and he's the one who can fix it. He looks more like a brigand than a powerful wizard or wise scholar, but with an important ceremony coming up, Fransisa decides it can't hurt anything to let him take a look at the Source.
Kaniev's disastrous attempt to repair Source Chaitrasse leads to a sorcerer who is conducting dangerous experiments with magic. Caught in the sorcercer's schemes, Fransisa and Kaniev must overcome their past failures and their differences to stop him before the Sources of magic and all the lands around them are destroyed.
