Despite knowing the danger, Violet and seven other cadets return to Basgiath War College. Their mission is to act as inside agents for the revolution.
Violet’s second year proves even more brutal than her first. The new Vice Commandant, Major Varrish, suspects her involvement in secrets.
He pushes her toward burnout during signet training. He watches her every move, looking for weaknesses to exploit.
Her relationship with Xaden also frays under pressure. She demands full disclosure and honesty from him.
Xaden insists on keeping secrets to protect the revolution. Their conflict over trust becomes a central tension throughout the year.
Meanwhile, Violet’s dragon Andarna enters a “Dreamless Sleep.” The time-stopping power she used at Resson triggered an accelerated growth process.
Violet works with her squad and the scribe Jesinia to research magical wards. They want to raise protective wards over Aretia.
Their research points to the journals of the First Six riders, hidden in a royal vault. In a daring heist, Violet, Xaden, and their companions steal the journals.
The initial translation suggests raising wards requires the “blood of the six” dragon breeds. Their first attempt in Aretia fails.
The situation worsens when Jack Barlowe resurfaces. Violet thought she killed him during her first year.
He was secretly saved and “mended” by Nolon. Later, it becomes clear Jack has turned venin.
During the winter solstice, Jack murders his own dragon, Baide. This act collapses the wards protecting Basgiath.
A massive horde of venin and wyvern attacks the college. The final battle is chaotic, desperate, and devastating.
Violet finally deciphers the true translation for raising the wards. It requires the “breath of life” of seven dragon breeds, not six.
She realizes Andarna is a unique seventh breed. Her dragon’s existence is the missing key.
General Lilith Sorrengail, Violet’s mother, makes the ultimate sacrifice. She allows her life force to be siphoned into the wardstone.
The wards rise. The battle is won. Basgiath stands.
But the victory comes at a staggering cost. In a desperate move to save Violet from a general-rank venin, Xaden draws power from the earth.
This act turns him into a venin. The book ends with Violet holding him, the future suddenly uncertain and terrifying.
