Caitlyn is looking forward to Midsummer's Eve in the tiny English village of Tillyhenge. Celebrating the summer solstice can be fun - especially when your grandmother is a witch with an enchanted chocolate shop But when a teenage girl is murdered and a priceless love potion goes missing, she and her cousins are plunged into a puzzling mystery.

Is the girl's death connected to the midnight bonfires at the ancient stone circle? What about the two strangers who recently arrived in the village? With her naughty black kitten and toothless old vampire uncle (not to mention handsome British aristocrat, Lord James Fitzroy ) all lending a helping hand, Caitlyn sets out to do some magical sleuthing.

But Midsummer's Eve is fast approaching and spells are going disastrously wrong... can Caitlyn use her newfound witch powers to find the killer - and maybe even mend a broken heart?
