A Fate of Wrath and Flame (Book 1). К.А. Такер

She would know the world of vengeful gods and monsters, and the lengths one would go for love. And nothing would ever be the same for her again.

Gifted thief Romeria steals jewels under a notorious New York City crime boss. But when an enigmatic woman secures her services at swordpoint, Romeria is wrenched from this world and transported into a realm of opposing thrones, warring elven societies and elemental magic.

Waking up in the body of a treacherous elven princess, Romeria quickly realises she's entangled in a deadly plot and must hide her identity at all costs - not least from the princess's betrothed, King Zander, who detests her. Romeria is forced to play the smitten princess as the unwilling pair work together to uncover the danger that surrounds them.

But with their enemies closing in - and as she fights her growing feelings for the king - it's time for Romeria to find out who she truly is.
