Summary: In a land where the power to yield light is a gift, Seyo is cursed with the power of fire. Her final request before she becomes a priestess is to set her eyes on the forbidden underground tunnels known as The Heart. But when unknown consequences lead to the death of a friend and a battle between nations, can Seyo escape alive before the Eternity Gate is opened?

Notes from The Radical Reader:

  • Noble Characters: Written from a first person point of view, the story draws you into this epic adventure of fire and light, mystery and intrigue, betrayal and suspicion. Seyo, the main character, knows that when she becomes a priestess in the temple, she must cleanse herself from her wicked deeds and stand holy in the Father of Light’s presence. But she has one final request before doing so, and this one final request could mean the end of the kingdom of Laijon.
  • Captivating Plots: Within the opening chapters of The Eternity Gate, I was hooked. Underground tunnels. Secret passageways. Forbidden treasure buried in the skeletons of sea serpents. When the ancient feuds of nations center around the kingdom of Laijon, only one girl knows where the Eternity Gate is, and only she has the key to open it.
  • Elaborate Worlds: Consistently throughout the story, I found myself loving how similar The Threshold Duology is to The Horse And His Boy by C. S. Lewis. In a Middle Eastern-inspired fantasy world, author Katherine Briggs has taken readers through deserts, palaces, and fire to bring them the epic story conveyed in this duology!
