Connelly, Clare. Royally tempted #1

Harlequin presents #4314

"One ring...to secure two royal heirs! King Octavio must marry a princess to protect Castilona's crown or risk civil unrest. Meaning a single wild encounter with cleaner Phoebe James is all he can allow. Then she drops a twin bombshell! There's no world where Octavio won't legitimize his successors, so Phoebe shall become his queen... For her babies' sakes, Phoebe accepts Octavio's diamond demand -- but it can't be more than an on-paper union. Accustomed to betrayal, she won't let his incendiary gaze persuade her otherwise. However, in the intimate confines of the palace, reason is overridden by insatiable desire!" --
