Royal Affair by Cristiane Serruya

She wants a night of wild fun to mend her broken heart–no commitment needed.
He thinks his life is complete–until she shatters his perfect illusion.

Princess Angelica de Castella y Aragon was left at the altar. Humiliated and heartbroken, she’s willing to give her V-card away to the first hot hunk who comes by…as long as there’re no strings attached.
Grand Duke Ludwig von Kröenenberg has everything: success, fame, money, women, and hotness in abundance…but he’s never found a woman enticing enough to keep his interest.
A feisty and forbidden week-long affair with the sweet, sassy, and sexy princess drops him to his knees. And when she leaves him without a goodbye, he becomes determined to win her heart…and her love.
Yet Angelica’s ex-fiancé is back, seeking her hand and the Aragon throne. If he gets in the way, the couple will have more to lose than each other–they could sacrifice an empire.
