On the brink of her quinceanera, and her official coronation, Solimar visits the oyamel forest to sit among the monarch butterflies. There, the sun pierces through a sword-shaped crevice in a boulder, which shines on her and sends the butterflies humming and swirling around her. After the magical frenzy, she realizes she’s been given a gift – and a burden: she can predict the near future! She has also become a protector of the young and weak butterflies. This alone would be a huge responsibility, but tragedy strikes when a neighboring king invades while her father and brother and many others are away. The remaining villagers are taken hostage – all except Solimar. Can this princess-to-be save her family, the kingdom, and the future of the monarch butterflies from a greedy and dangerous king?
