Bound By The Night - Xaden Riorson

No one knew where the High Lord's sister went.
Not even him.
Velentina, the younger sister of Rhysand of the Night Court, vanished under the cover of starlight-sent away for her own protection. She awakens in a realm unlike any she's ever known: a world without Courts, without fae magic... and without a single whisper of Prythian's existence.
Navarre knows nothing of her realm.
And she knows nothing of theirs.
Determined to survive, Velentina learns their ways-training, fighting, and hiding what she truly is. But danger pulses through this land: dragons that choose their riders, generals who wield deadly power, and a kingdom built on secrets and fear.
And through it all, she can feel it-eyes watching from the shadows, waiting for her to remember who she truly is.
Because the truth cannot stay buried forever.
And when it surfaces, Navarre will learn what it means to cross the sister of the Night Court.
