The Iron Wolf and the Nightingale

He is the Empire's most ruthless weapon. She is a northern captive trapped in a political nightmare.
General Zhao Xiangrui-the feared "Iron Wolf" of the Great Imperial Dynasty-has spent a lifetime bleeding for a throne that views him as a deadly monster. Clad in heavy black armor, with a face scarred by war and a heart hardened to ice, his mandate is simple: march north from the imperial capital, crush the rebellious frozen borderlands, and secure the territory for the crown. He has never known mercy, and he has never failed a campaign.
Katrena is a proud survivor of those unforgiving northern wastes. With hair as black as winter nights and striking, piercingly cold grey eyes, she belongs to the snow. But when her homeland falls, she is ripped from the north and forced into a miserable, arranged political marriage to a cruel, arrogant nobleman from the south-a man who views her as nothing more than a trophy to break.
Trapped in a snake pit of imperial court politics and bound to a husband she despises, Katrena's only hope for survival rests in the hands of the very man who conquered her lands: General Xiangrui.
As a deadly conspiracy threatens to tear the empire apart, the brutal general and the sharp northern captive are drawn into a treacherous, unspoken alliance. Bound by dangerous chemistry and a shared hatred for the court's corruption, they must play a high-stakes game of betrayal. Xiangrui represents everything that destroyed her home, but he might be the only man fierce enough to tear her away from the southern elite who want to break her wings.
Can a wolf protect a nightingale from the predators of the court? Or will the fires of the imperial capital consume them both?
