Magic has broken free, and the world is in grave danger. Jayne Thorne, CIA Librarian and secret operative, thought finding her father would solve everything. She couldn't have been more mistaken. Henry Thorne is a prime target for all her enemies, and everyone around him is in danger. Though Jayne's powers are reaching new heights, she must contend with her reluctant new Rogue, Vivienne, her inconvenient and growing attraction to her partner, Tristan, and a prophecy from an unnamed warrior goddess that warns her of the impending danger from the Torrent's powerful hidden mage who is controlling her mother, Ruth.
Not to mention face down an ancient secret society tasked with protecting a grimoire vital to their cause. Meanwhile, Jayne's sister Sofia and her Rogue Cillian, along with other members of the TCO (the magical branch of the CIA), are searching for the newly magical children who are making news all over the country. But they are not the only ones with this mission. Sofia and Cillian must find, protect, and educate as many new Adepts as possible before dark forces steal their powers. With the help of her friends, family, and new allies, Jayne must decipher the prophecy, acquire the grimoire, and stop the powerful mage hidden in the Torrent.
But even with their help, Jayne is not sure if she will be able to succeed. The enemies of the Torrent grow more powerful by the day, and they are relentless...
