How Not to Marry a Prince — Megan Derr

At the ancient, doddering age of thirty, it's long past time Prince Amador married, at least according to his domineering family. Determined to see the matter attended at last, they have issued an ultimatum: find a betrothed before the year is out, or he'll be sent off to marry Prince Ottokar, Crown Prince of their oldest enemy, a man Amador has hated and feared for nearly all his life.Desperate to avoid that fate, he has one last chance: to win the affections of Prince Nazaire, who has notoriously turned away every single suitor barely before they make their introduction. When he arrives, though, Amador finds not a snooty prince impossible to please, but a castle so brimming with secrets and romantic pining that the whole mess would be worthy of a bard's tale.If there's one thing Amador loves more than mischief, it's romance. He won't ever be happy in his own marriage, but here's a chance to see that others will be happy in theirs—and if he's lucky, they'll all be so pleased with the results that the quiet, handsome King Sohan will insist that he remain to help with other matters.
