The High Queen's Vow, Book IV in the Mystic Women of The Realm series, picks up right where Book III left off. Leaving Sansthera, The High Queen begrudgingly accepts the battles they face throughout their journey so she can complete one of her sacred vows - to return the Elves to The Realm. Finding clues she needs along their journey, The High Queen and her forces enter into The Wastelands, where they discover The First High Queen's chamber of mystic powers long lost to The Realm. But they also come face-to-face with The High Queen's well-loathed past, as well as rescue a piece of The High Queen's future. The quest to restore the long-lost Elves to The Realm is a goal The High Queen is determined to win, but the journey to El'fs'nd'lle offers her challenges beyond any other she has faced. Yet even as she completes this most sacred vow, and even after the enormous toll of their battles during the journey, she soon learns that her greatest challenge is just awakening and the ensuing Battle of the Eons against the Wizard of the Ravens will place all their lives in the balance. Knowing the great odds against her and her forces, she is told two things by her Seer: There is usually a reason for dark moments such as this; and The Realm will not exit this battle as they enter.
