On midsummer's day, Phoebe Bowler - star-sign diva - should have returned to her pretty garden flat as an ecstatically happy new bride. Instead, she's been jilted at the altar. In need of sympathy, she turns to her upstairs neighbour, the dishy Rocky Lancaster. But with problems of his own he's turned into Mr Grumpy and wants to be left alone. Phoebe's only too happy to do just that. After all, when your life has fallen spectacularly apart there really isn't room for anyone else's problems, is there? However, when Rocky and Phoebe meet Essie Rivers, their astral paths seem destined to collide with a very big bump. Essie knows far more about astrology, personolgy, numerology - any ology you care to mention - than Phoebe has ever heard of. But it is Essie's secret magic of birthdays that captures Phoebe's imagination. Can she really use a birthday to find a perfect match or to set her and Rocky back on their separate paths to happiness? Phoebe thinks so, which is when things really start to go wrong...
