Adamant

<p>Ever since a devastating magical war tore apart Ada Fletcher's homeworld she and her family have lived undercover on the low-magic Earth. Stuck in a dead-end job in London Ada has spent her life hiding both her true identity and her forbidden magic from the Inter-World Alliance: the organisation that polices the Passages between Earth and its magical neighbours.</p><p>At least until a high-ranking Alliance official is murdered and Ada is arrested as the main suspect.</p><p>Kay Walker grandson of the Inter-World Alliance's late founder expects to spend his first week as an Alliance employee hunting rogue monsters in the Passages not solving his supervisor's murder. However the main suspect is a fierce young woman with dangerous magic from a world that should no longer exist... and the closer Kay gets to uncovering the truth the higher the body count rises.</p><p>The last thing Ada wants to do is help the infuriating Alliance guard who arrested her but it soon becomes clear that the Alliance knows too much about Ada's homeworld -- and her magic. More in fact than she knows herself. One thing's certain: she's not the only one keeping secrets and trusting the wrong person might cost more than her life.</p>
