Her father left her a key, a riddle, and a destiny she never asked for.
Seventeen-year-old Ellyce Jensen has spent her whole life being skeptical of the supernatural, which makes it especially inconvenient when her father vanishes and leaves behind a mystery she can't explain away. A hidden room. Ancient artifacts. And mysterious versions of the same novel, each one a map to a realm that shouldn't exist. Thomas Jensen wasn't just a writer. He was a guardian. And Ellyce? She's the last heir of a bloodline with one impossible mission: unite seven fractured supernatural kingdoms before a war that's been building for centuries finally breaks open. She doesn't want this. She doesn't believe in prophecy, celestial warriors, or ancient promises made on her behalf. But when the darkness her father warned her about starts bleeding into her world-and her ex-best friend Benson turns out to know far more than he's ever let on-Ellyce realizes the choice isn't whether to believe. It's whether she's brave enough to answer. One girl. Seven realms. A promise that could save them all. The Promise is Book One in A War and A Wedding-a seven-book YA supernatural bloodline mystery series where ancient bloodlines, celestial prophecy, and a destined love collide.
