When Earth suddenly gains inexplicably high levels of magic, all fingers point at the Alliance. On a distant world, where magic-fuelled forces of nature rule over humans, a disaster is sweeping the land, threatening to knock the Balance across the Multiverse out of sync. When Kay and Ada are sent there with the other Ambassadors, they’re thrown into the centre of chaos. Nature is alive, and angry. Ada embraces the magic she still half-fears, but learning to control it proves harder than she can imagine. Kay, meanwhile, becomes more reckless than ever when testing the boundaries of his own abilities. When faced with living magic, no one is safe from its influence. Ada and Kay must choose what they’re willing to risk for the sake of saving a world that might already be doomed. Can mortals overcome the gods? Collision is the third book in the world-hopping urban fantasy Alliance series.
