Aunt Enid: Protector Extraordinaire — Karen J. Carlisle

Daemons, fairies, magic: it's all real!
The Otherworld is bleeding through cracks into our world. And Adelaide is ground zero. Something is coming. Something dark - trading souls for passage. And only one person stands between The Dark and the fate of the world.
Aunt Enid is just your average seventy-something year old. She loves to cook, is a regular at bingo and spends hours in her garden, talking to her army of garden gnomes and fussing over the colour of her hydrangeas...
When people start disappearing, her great niece, Sally, is drawn into a secret world and soon discovers her great aunt is a Protector Extraordinaire. Aunt Enid: Protector Extraordinaire is the first book in 'The Aunt Enid Mysteries', the first series in 'The Otherworlds Chronicles'.
