Emry Merlin should be living her best life as a wizard's apprentice. Now that she no longer has to pretend to be her brother to study magic, she and Prince Arthur are closer than ever. Except King Uther has warned her to stay away from his son, and Emry's magic is growing more unpredictable by the day.

Meanwhile, Arthur's prophesied future as the One True King is closing in. And as his wedding to Princess Guinevere draws nearer, he discovers she's hiding a shocking secret. When Emry learns that the only hope to fix her increasingly dangerous magic is an eccentric Parisian alchemist, Arthur has his own reasons for accompanying her to French court, and for befriending an infamous crowd of young nobles.

But it's going to take a lot more than a depressed gargoyle, some obscenely tight trousers, and a deadly sports match to keep our young heroes from their destiny. Can these reluctant royals and wayward wizards set aside their drama and save their kingdom, or is Camelot doomed?
