The Queen's Crown (League of Rulers, #1)

Her sister’s wedding was meant to unite two kingdoms.
Her murder ignited a war in Sabine’s heart.

To hunt the killer, Princess Sabine Ludwig takes her sister’s place and weds the enigmatic king of Lynk—a man whispered to be as ruthless as he is devastatingly charming. She plans to seduce the truth from him, then spill his blood if she must.

But the king’s touch is a temptation she never expected, and every glance from him blurs the line between enemy and lover. In a court where loyalty is bought with lies and desire is a weapon, Sabine must decide which is more dangerous—trusting the wrong man, or falling for him.

One will ruin her.
The other will destroy her kingdom.
