Synopsis
After bringing down the Thulcaan Empire, Jack Valantier dies—only to awaken in his fourteen-year-old body. Back in the noble household that shaped his earlier life, he remembers every betrayal, including the cruelty of his family and the support of those closest to him. With years of hard-won knowledge on his side, Jack prepares to confront his enemies before they can repeat the past.
