Starfell 01: Willow Moss and the Lost Day

Misfit witch Willow Moss holds the fate of the magical world of Starfell in her rather unremarkable hands . . . A spellbinding new fantasy series for readers aged 8-12, perfect for fans of Cressida Cowell.
Willow Moss, the youngest and least powerful sister in a family of witches, has a magical ability for finding lost things - like keys, or socks, or wooden teeth. Her magic might be useful, but it's not exactly exciting . . . Until, that is, the most powerful witch in the whole of Starfell turns up at her door needing Willow's help.
A whole day - last Tuesday to be precise - has gone missing. And the repercussions could be devastating. Can Willow find the day to save the day?
