Big Magic

Eleven-year-old Tulsi comes from a long line of women magicians; but her mother has always forbidden her to learn Big Magic. It's dangerous; thrilling; and powerful – and Tulsi wants it more than anything. But one hot summer's night; a magic trick goes horribly wrong; and her mother disappears. Only one person can bring her back; and that's Tulsi.
 
But first; she'll have to learn a lifetime's worth of Big Magic – in just one month.  It's an impossible task; especially when her teacher – her strange grandmother; Sylvie – was long ago banned from doing any Big Magic at all. Tulsi is determined to save her mum; but does she have what it takes? And where; exactly; has her mother gone?
