A GAME OF CAT AND MOUSE SPANNING THOUSANDS OF YEARS IS COMING TO A HEAD. As the Legacy of the Watchers continues, Nadia finds herself inextricably tied to the Raphaelians. Her former life — and everything she believed in — has been shattered, and she needs their help to pick up the pieces and start again. But there are still unanswered questions, so Nadia is once again drawn into the mysterious underworld of the hidden ones. But now there may be even more at stake. Threats of Armageddon loom in the distance as they attempt to decipher a formula that may hold the key to unconscionable power. Their quest takes them back to the ancient world — this time to King Solomon and his legendary djinn. Meanwhile, thousands of miles away, Lilith is already attempting to finish what Asmodeous started.
