Masataka is a shape-shifting neko who makes the unfortunate mistake of picking up a stunning kitsune at a bar and taking her home for the night. How was he to know it was her wedding day? Or that her chosen mate was a nine-tailed kitsune of great distinction and power? Masa's punishment is to be banished to Earth, stuck in his cat form until someone wishes for him to stay.

If it weren't for bad luck, Effin wouldn't have any luck at all. It's Valentine's Day, a day supposed to symbolize love and romance. Instead, it's the worst day of Effin's life. Whatever could go wrong, does. Abandoned in the middle of nowhere, Effin finds a homeless kitty. Charmed, she takes the cute, furry creature home.

It just so happens that the pretty kitty is actually Masataka, that lucky, lusty, shape-shifting neko. Suddenly, bad dates, worse clothes, and the sister from hell are a thing of the past.

Effin is the woman of Masataka's dreams. Effin's not so sure. It's up to Masataka to convince Effin to believe in the staying power of love... and in her sexy lucky charm.
