Fury of Frustration by Coreene Callahan

Ambition can be deadly…
Born of a powerful god, but exiled on earth, dragon-warrior Kruger conceals the truth of his origins from the world. Forced to live a lie, he proves his worth by becoming a tycoon in a powerful business empire. But when a beautiful woman with ambitions of her own gets in his way, he must decide—accept what he cannot change, or eliminate the threat once and for all.
Haunted by ghosts, Ferguson McGilvery needs out. Out from under her step-father’s thumb. Out of the toxic whirlwind her step-brothers create. Out of the country, far away from the dysfunction that has overtaken her life. When a surprise inheritance sends her to the Scottish Highlands, she clashes with Kruger, a man so infuriating she’ll do anything to foil his attempts to make her leave.
His ruthlessness is legendary. Her obstinance knows no bounds. Can two stubborn souls go from enemies to lovers…or will the fates finally admit they made a mistake by throwing the pair together?
