A royal, marriage of convenience, pregnancy romance by Lorraine Hall.

A secret to claim
A queen to conquer

King Alexandre wed Ines solely to secure a royal baby. Except now he has a nephew, he no longer needs his own heir. So his usually compliant wife’s ultimatum—give her the child he promised her or she’ll leave—astounds him. And her fiery declaration finally forces him to face their incendiary need…

After their passionate encounter, Alexandre is relieved by Ines’s unexpected departure from the palace. At last, a reprieve from her assault on his ironclad self-control! Until he learns Ines is pregnant. Alexandre will demand what’s rightfully his, including his queen!
