How to catch a witch - Abie Longstaff

Charlie and her family have moved from the big city to a small country
village, and everything feels wrong. The cottage they now live
in is old and creepy. Anxiety about her new school is causing
Charlie's stutter to return. And the villagers are just plain weird:
Beautiful young singer Suzy Evans, who glows with a strange
light that only Charlie can see. Mysterious classmate Cat, who won't
keep her nose out of Charlie's business. And Agatha, who may
not have a broomstick or a cauldron, but is definitely a witch...
Slowly and steadily, though, the strange surroundings exert their
effect on Charlie... Would a bit of Agatha's magic fix her worsening
stutter? Nothing else seems to...
But bad-tempered Agatha has long since retired from magic. Besides,
she tells Charlie, her stutter is part of who she is, not a curse
that can be removed. Not like the curse that's been put on Suzy
Evans, the sparkling singer, who is set to lose her wonderful
voice when she turns sixteen in just a week's time...
