The Call of Fire by Sloane Calder

The only thing more dangerous than their love? Thinking they might actually survive it…

Elspeth Lennox arranges the Natura world’s most powerful unions every day. But her own love life? That’s way more complicated. Her bloodline (and lack of elemental powers) ensures that she won’t get a fairy tale ending. A mutually beneficial arranged marriage is probably the best she can do. And she’s mostly OK with that…until she meets her inconveniently sexy new bodyguard.
Fire elemental Aleron Foussé will have his revenge. Protecting Elspeth will give him the cover he needs to finally bring down his father’s murderer. Elspeth is just a pawn. He knows that. But knowing doesn’t stop him from wanting. Love, family…things he hasn’t dreamed of in years. Now he wants it all. He wants her. Too bad a union between them is as forbidden as it is ill-timed…
Enemies are circling. The threat of civil war looms large. Only one thing is certain—there’s a lot more at stake than Elspeth and Aleron’s happily ever after. Because when all is said and done, lives will be lost.
They can only hope it’s not theirs…
