The Alliance Series Books 1-3 - The 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. Ever since a devastating magical war tore apart Ada Fletcher's homeworld, she and her family have lived under cover on the low-magic Earth. Stuck in a dead-end job in London, Ada has spent her life hiding her true identity and her forbidden magic from the Alliance.
until she's accused of a crime she didn't commit and taken into Alliance custody. The last thing she wants is to help Kay Walker, son of the absentee council member responsible for exiling her homeworld from the Multiverse, but when circumstances push them into an unlikely truce, there's no going back. Ada and Kay face rampaging wyverns, power-hungry magic-wielders, and enraged centaurs hell-bent on declaring war on their human neighbours.
The wonders of the Multiverse await them. if they can survive the storm that's coming. This boxed set includes the first three novels in the world-hopping Alliance series: Adamant, Nemesis and Collision.
