Iron Heart of Terlian

Earth was green once... before the Lykill vanished. They call it Ragnarök. Soon, there'll be nothing green left. Violet's father believed Earth could heal. But he also believed in forgotten legends, magic, and other worlds, so she never put any stock in his impractical theories-until she accidentally stumbles into one such other world and realizes Earth isn't the only realm desperate for hope. An exiled royal family. A disillusioned prince. A fathomless hatred of Earth. Magic thieves and lawless thief-hunters. None of it is what Violet bargained for. She just wants to find Earth's cure, not get embroiled in the political tensions of another planet. But Earth's fate is tied to a thousand-year-old prophecy, one that a desperate vigilante is trying to exploit. When he attacks her new companions, they're forced to race him to the cure. If they don't find it first, their world will fall-and Earth is as good as dead. From the author of the Whitewashed trilogy comes a portal fantasy duology for lovers of layered world-building, witty banter, and strong themes of friendship, healing, and hope.
