What’s it about?

The story.

Mary Anne finds a mysterious chain letter and a bad-luck charm, and soon strange things start happening. Is she really cursed, or is someone trying to scare her? As Mary Anne worries about unlucky signs and suspicious events, the rest of the Baby-Sitters Club has to help her figure out what is going on. This thirteenth Graphix adaptation, illustrated by Cynthia Yuan Cheng, brings a mystery flavour into the familiar BSC world. It is not frightening in a horror sense, but it does add light suspense, superstition and anxious what-if thinking to the usual friendship-and-babysitting structure. For children who enjoy puzzles, secrets and a little safe spookiness, this is a useful entry. The emotional core remains very Mary Anne: sensitive, cautious and brave when she needs to be. Best for existing BSC readers who want something slightly different.

Why it lands

Why they love it.

Why kids love it

The specific charm is mild spooky — Mary Anne finding strange tokens, a chain letter, the feeling of being followed by bad luck. A ten-year-old gets a properly satisfying mystery played at low enough peril to read in bed without nightmares. Mary Anne's anxious POV gives it tension.

  • Being a detective
  • Friendship and belonging
  • Making a difference
  • Proving yourself
  • Surviving danger

Why parents love it

The BSC for the spooky-curious reader — light mystery, low peril, no actual horror. Mary Anne's anxious POV makes it tighter than it could be. Good change-of-pace BSC; useful seasonal Halloween-week pick that won't tip into nightmare territory.

  • Nostalgia
  • Quick to read
  • Shared humour
  • Bedtime appropriate
