The Spy's Twisted Magic

Persephone Thornton comes to her cousin Jasper's house to spy on him for the Welsh freedom-fighters and is unprepared for how much she comes to like Jasper and his wife, Delia.

Mage gifts decide power and status in their Regency society, but Sephie's gift keeps twisting toward flawed results until Taliesin Ddraennen, a gardener in Jasper's employ and her contact from Wales, shows her how to use it without that flaw.

Taz was raised by the resistance and has spied since he was sixteen, never before set to work with a lady of the English aristocracy; he soon values her resilience and intelligence more than her sharp temper, and his erratic magic settles when the two of them sing.

Discovery of a spell meant to overhear the dragon lord's meetings puts the blame on Sephie, and Taz will not go without her, so their escape runs through England's ancient forests to the fae, where they learn the real nature of their mage gifts.

Back outside that realm, the new bond between them is tested at once: Taz must weigh Sephie against Welsh freedom while war spreads and any peace that lets them choose one another seems out of reach.
