A royal engagement in the seaside kingdom of Alameda has the makings of a fairy tale. And for Princess Annabelle of Sereno, her life-long friend Princess Tayla's happy news is the perfect excuse for a visit. Annabelle arrives in full wedding-planning mode, but her enthusiasm is cut short the moment she steps off her yacht and spots a less-than-friendly face. Of all the people who could have jumped in to escort Annabelle to the castle, why did it have to be him?

Retrieving his sister's annoying childhood friend is the last way Prince Leo would choose to spend his time, a sentiment that Annabelle clearly shares. But there's no time to dwell on their mutual dislike. Moments after her arrival in Alameda, Annabelle's luggage detonates, and the two royals barely make it out alive. Despite their long-standing animosity, Leo and Annabelle have no choice but to work together to discover the culprit and prevent another attack. As danger presses in on every side, the former foes soon discover that they may have been mistaken in their opinions of each other. But there are more pressing concerns than their shifting feelings because one thing is clear: someone is trying to kill the Alamedian royalty, and until they can uncover who it is, no one is safe.
