While her mum struggles to hold down a new job, Becky has to amuse herself in the long, hot summer holiday before starting her new school. She finds an old photo in a box under her mum's bed but is unable to find the right time to question her mum about what it means. So she bides her time by spending her days at the Butterfly Garden, a nearby attraction where a girl called Rosa May becomes her best friend. But even she isn't all she seems.

This is a ghost story. It's a very enjoyable read (I polished it off in a couple of hours) but having just read 'Daylight Saving' by Edward Hogan, the story held no surprises for me; they are remarkably similar in premise. And having also recently explored 'A Woman in Black' and 'Small Hands' by Susan Hill, I feel I've had my fill of ghosts seeking revenge, or challenging the accepted notion that they should appear at night in the cold and fog. But this is a book for girls aged 10+, and it is likely to prove a great read which will keep them puzzling and wondering for days after putting the book down.
