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