Master of the Royal Secret
From Wall Street Journal bestselling author Jeff Wheeler comes the heart-racing conclusion to the Invisible College series. The fate of the world hangs in the balance as two star-crossed lovers fight to beat impossible odds and secure a future together, and for humanity, or risk an all-consuming winter.
A bargain was struck beyond memory, sealed by an immortal covenant that promised either peace or extinction for humanity. The Aesir will uphold this covenant, whatever the outcome, but the Erlking will do everything in his power to ensure their victory. Two people hold the key to defeating him, but only one of them remembers who they are.
Everyone believed that Robinson Hawksley perished when the Aesir attacked the university at Nirshoye. But with memories unlocked, he now remembers the past and must await the final Awakening of the Aesir. When he revives from a magical sleep, he discovers that the Invisible College is in shambles, that those who practice magic are persecuted and put in debtor’s prison when they cannot pay the exorbitant fines leveled against sorcerers.
To end the coming calamity, Robinson must discover where the Erlking’s daughter is currently a Semblance, a doppelganger living among mortals but not knowing her true identity. It will take every creative instinct and an indefatigable purpose for the last sorcerer of the Invisible College to achieve the impossible. To thwart the Erlking himself who has finally come among mortality in a guise of his own.
There can only be one Master of the Royal Secret.

Jeff Wheeler
Jeff Wheeler’s writing journey is as much about personal transformation as it is about the intricate worlds he weaves. Born in the heart of the Silicon Valley, Jeff was immersed in technology from a young age, a background that contrasts with the sweeping fantasy realms that now define his work. But the marriage of the two—his technical mind and his boundless creativity—has made him one of the standout authors in modern fantasy.
After earning degrees in history and business from San Jose State University, Jeff carved out a successful career at Intel Corporation, but his passion for storytelling never waned. What started as late-night writing sessions grew into something more. Inspired by fantasy legends like Terry Brooks’ The Elfstones of Shannara, Jeff realized that he had stories to tell—stories of magic, power, and deep emotional journeys.
The Invisible College
In a world where magic and music intertwine, The Invisible College is a fantasy series that challenges the boundaries of what we know about both. The first book takes readers into a 19th-century-inspired world where knowledge, power, and sound converge in an extraordinary system of magic. Here, sorcerers don’t wield wands but instead channel the Unseen Powers through speech and melody—an ancient form of magic hidden in plain sight.
The Invisible College consists of four books — considered a complete series. The current recommended reading order for the series is provided below.
