Quicksilver by Callie hart

This #1 New York Times bestseller is a highly addicting enemies-to-lovers Romantasy with razor-sharp banter, heart-stopping action, and blistering hot romance.

Do not touch the sword. Do not turn the key. Do not open the gate.

Twenty-four-year-old Saeris Fane is good at keeping secrets. No one knows about the strange powers she possesses, or the fact that she has been picking pockets and stealing from the Undying Queen’s reservoirs for as long as she can remember. In the land of the unforgiving desert, there isn’t much a girl wouldn’t do for a glass of water. But a secret is like a knot. Sooner or later, it is bound to come undone.

When Saeris comes face-to-face with Death himself, she inadvertently reopens a gateway between realms and is transported to a land of ice and snow. The Fae have always been the stuff of myth, of legend, of nightmares…but it turns out they’re real, and Saeris has landed right in the middle of a centuries-long conflict that might just get her killed.
