Bewitching the Dragon by Tami Lund

Her job: Save the world.
His job: Don’t tell her that she’s supposed to save the world.
Complicated? You betcha.

Becca Jorges has no freaking clue she isn’t human.
But Rahu Volos does.
He knows all about her supernatural side.
And he’s sworn to secrecy,
which isn’t good for their budding relationship.
It’s also not good for the entire world.
Because Becca is the only one who can save it.
