Happy Birthday - The perfect grumpy x sunshine romantic comedy

One midsummer's day, Phoebe Bowler - a star-sign demon - should have returned home an ecstatically happy new bride. Instead, she's been jilted at the altar. In need of sympathy, perhaps she could turn to her neighbour, the dishy Rocky Lancaster? But, with problems of his own, he's turned into Mr. Grumpy and wants to be left alone. That is until Essie Rivers arrives on the scene, and Phoebe and Rocky's paths seem destined to collide with a very big bump.
Essie knows far more about astrology, person-ology, numerology - any '-ology' you care to mention - than Phoebe has ever heard of. But it is the secret magic of 'birthday-ology' that catches Phoebe's eye. Can she really use a birthday to find her perfect match, or set her and Rocky back on the path to happiness? Phoebe thinks so, but that's when things start to go really wrong .
