"If you only read one children's book this summer... make it this
one" The Guardian

A brave, bright girl embarks on a heart-racing adventure to find
her missing father - with magic and danger quite literally in the
air...

Twister's beloved father has gone missing and as she's searching
for him she stumbles across a witch living in the woods. She is given
a magical necklace that holds the souls of living things and
can turn the wearer into a wolf, or a rushing river, or a rainstorm.
But there's a dark foe on the hunt for this necklace, a baddie
who wears a coat crawling with creatures and who might have something
to do with her father's sudden disappearance...
