Rune Saint John is the last scion of the Sun Throne-one of New Atlantis's ancient ruling Arcana, a spell-caster of terrifying power, and, right now, the man trying to pack two luxury RVs with his entire found family for an American road trip. What starts as a chance to heal and put recent losses behind them becomes something far more dangerous: a reckoning with new and organized enemies, murdered fae, and truths that refuse to stay buried. Racing from one mystery to the next, Rune and his companions follow a trail of violence toward Sanctuary City, the secret underground stronghold of the mainland fae. There, Rune confronts revelations that crack his world open. As loyalties are tested and safety unravels, he realizes the most dangerous lies aren't the ones told by enemies-they're the ones stitched into the lives of the people he loves most.
