For thirteen-year-old Rose Gallagher, having a friend who is really a dragon and can perform magic, change shape, and fly her away from the predictability of small-town life feels like a dream come true. But secrets have a price, and the more Rose learns about her friend Jade and the world of dragons, the more dangerous her life becomes. Helped only by her fantasy-obsessed friend and a local occult enthusiast, Rose soon finds herself risking her life to help Jade recover a mysterious fragment of a meteorite called the Harbinger, which has the power to awaken countless dragons from their sixty-five-million-year slumber. Can they find the Harbinger before Jade’s enemies? As their battle unfolds over the neon-drenched skies of Las Vegas, Rose must face this overwhelming threat by drawing on the magic that humans possess—the power of friendship, compassion, and trust.
