Adamant

Two worlds collide... literally.

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. At least until she's captured by the Inter-World Alliance and framed for a deadly magical murder she had nothing to do with.

Kay Walker, grandson of the Inter-World Alliance's late founder, expects to spend his first week as an Alliance employee hunting rogue monsters, not solving his supervisor's murder or questioning a strange, fierce young woman with dangerous magic. Killer or not, her abilities raise questions about the Alliance's history, and the closer he gets to the truth, the higher the body count rises.
