Riley Sullivan writes instructions for assembling furniture, and that’s about as exciting as it gets in her workaday life. That is, until a twist of fate whisks her away on a cruise, where she meets Killian, the impossibly handsome lead singer of Irish Thunder. Her monotony vanishes with the roiling seas when she unlocks an adventure with this charming celebrity whose world is completely opposite from her own. Killian's passion is performing, but financial struggles force him onto a cruise ship where he meets Riley. Despite their instant connection, Killian's contract forbids him from mingling with the passengers, putting a damper on pursuing the woman he believes to be his soulmate. He can't shake the feeling they're meant to be together, even when fate is determined to keep them apart. With a lively blend of humor and musical chemistry, Riley and Killian navigate their mutual attraction only to discover their love could remain a fantasy forever. But when the heart knows what it wants…anything is possible.
