An Endless River (en Inglés) - Margaret Collins

Boston, 1895. When magic manifests in Grace Mackenzie, it does more than destroy her scientific career: it makes her prey. Only the Imperium, a society hidden in plain sight that governs wild magic, can offer her safety. Her flight throws her in the path of Konstantin Navarre, a disgraced dragon-shifter who sees Grace as an opportunity to regain his lost status.

But safety, even among the gilded halls of the Imperium’s stronghold in Newport, Rhode Island, is an illusion. Grace suspects she is a river mage, inheritor of a dangerous magic believed to have been long exterminated - and she is not the only one whose identity threatens the Imperium’s order. As her connection with Konstantin deepens from uneasy alliance into something neither of them planned for, Grace faces a choice. She can hide her true nature and finally belong somewhere that accepts both her mixed-race heritage and passion for science, or embrace it...and face the punitive wrath of the most powerful mages of the Imperium.

An Endless River is an historical fantasy romance at the intersection of magic, identity, and desire.
