Matched to a Prince [EPUB ebook] 

How could she be his perfect match? Prince Alain "Finn" Phineas pledged his love to Juliet Villere once—and she betrayed him. Despite the desire he still feels, Finn would never act on those feelings again. Not even when Juliet is chosen for him by an elite matchmaker. Then fate, in the form of the royal family, intervenes. Trapped alone on a beautiful island, they are held "captive" until Finn can convince Juliet to marry him and end a political nightmare. His motives should be about serving his country. So why does his heart yearn for a second chance with Juliet…a real chance this time?
