The Frozen Heart of Frostbridge is the second book in The Night of Twin Footfalls trilogy, continuing the tale of Krax, a man bound between two identities-one he forged through choice, and one carved into him by the ancient will of the sanctums. Frostbridge stands on the brink of renewal or ruin as forgotten machines wake beneath the mountain, drawn to the spark within a single child. When Weft is taken by a second, perfected anchor, Krax and his allies descend into the Pale Deep, uncovering truths buried for centuries. As ancient doors open and new enemies rise, the fragile line between destiny and defiance becomes sharper than ever. The story blends dark steampunk fantasy with post-apocalyptic myth, exploring identity, loyalty, and the weight of inherited purpose. This book sets the stage for the climactic finale of the trilogy, where the mountain’s deepest secrets-and the truth of Krax’s creation-will finally be revealed.
