Adamant is the first in the world-hopping urban fantasy Alliance series.On an alternative 21st-century Earth in which our world is one of many in the Multiverse, the Inter-World Alliance exists to keep the peace between the worlds, and keep the monsters out.Ada Fletcher is twenty-one, keeps a collection of knives in her room, and lives under the Alliance's radar in London, risking her life to smuggle people away from a devastating magical war on her homeworld to hide on the low-magic Earth. But when she's forced to use magic to defend her family and is caught by the Alliance, she becomes a prime suspect for a murder she had nothing to do with.Kay Walker, grandson of the Alliance's late founder, expects to spend his first week as an Alliance employee chasing monsters out of the dark Passages between worlds, not solving a murder or questioning a strange, fierce young woman he arrested in the Passages. Killer or not, she stole a highly dangerous object tied to a dark time in the Alliance's history. The closer he gets to the truth, the higher the body count rises.The last thing Ada wants is to help the infuriating Alliance guard who arrested her, but it soon becomes clear that the Alliance knows too much about Ada's magic. More, in fact, than she knows herself. Now she has to choose between loyalty to her family, and helping the Alliance save the Earth - and the Multiverse - from a deadly enemy.
