Cattle King's Mistress by Emma Darcy

Nathan King, powerful head of his legendary family’s cattle empire, has everything-except a woman to share his life. Miranda Wade has nothing — except a past she is determined to leave behind, and the hope that her new job at King’s Eden will give her a fresh start.

Their two lives collide! Nathan wants her, but doubts she will cope with outback life. Miranda wants him, but believes her past will deny her any chance at a future with a King. The tension — the need — between them is overwhelming, regardless of where it might lead.
