Forced to marry the enemy prince in her sister's place

When the ruthless empire of Aurelia demands a princess in marriage to secure peace, Princess Hera is sent across the sea to compete for the hand of a prince she has never met. At her side is her sister Astrid, a warrior forged in secrecy, trained not for courtly games but for bloodshed and strategy. Tasked by their father to protect Hera at all costs, Astrid enters a world of deception, where alliances are fragile and every smile hides a blade. But as Hera rises through the brutal courtship trials, fate takes a dangerous turn, she falls in love with another man… and carries his child. With war looming and scandal threatening to destroy everything, the Aurellian prince makes an unexpected demand: Astrid must take her sister’s place. Bound by duty, Astrid is forced into a marriage she never wanted, to a man she does not trust, in an empire built on conquest and greed. Now trapped at the heart of Aurelia, she must navigate deadly politics, protect her sister’s secret, and survive a husband who may be far more cunning,and far more dangerous,than she ever anticipated. — Description from novelcodex.org
