The Immortal's Dawn (An Epic Fantasy Romance): Book 1 of the Immortal and the Emperor Series by K. L. Kaye

Lián has survived eight centuries, seventeen dead emperors, and 645 deaths. None of that prepared her for what her own body does next. She's carrying a child — the first in eight hundred years she's let anyone close enough for that to happen. The court has opinions. The dragon has advice. The cat has claimed her stomach as personal territory. And somewhere in the shadows, the Hungering King is paying very close attention to what grows inside her. Because Lián's bloodline is the one he's been waiting a thousand years for. And now there are two of them. Staying was supposed to be the hard part. Turns out, it was just the beginning. The Immortal's Dawn is for readers who love found families forged in chaos, slow-burn romance that catches fire, and the discovery that the scariest thing an immortal can do is build something mortal. Features one dragon in aggressive denial about his feelings. One cat at war with an unborn child. And the growing suspicion that 642 reasons to run were easier than one reason to stay.
