Jenny and her friends - the Spellcasters - are excited about helping Aunt Connie in the Spellcroft community garden. But everything's going wrong... plants are dying, and the lake at the nature reserve dries up. Could it be the work of a dark witch? It's time for the Spellcasters to band together again and use their ancestral magic to find a way to fix the problem before the balance of nature is destroyed for ever!
