Welcome to another installment of our author interview series, “5 Questions with…” This time around, we’re talking with Spooky Middle Grade’s Mary Averling, author of THE CURSE OF EELGRASS BOG (January 2024) and the brand-new spooky story, THE GHOSTS OF BITTERFLY BAY, which just came out this week!
1. Mary, tell us about THE GHOSTS OF BITTERFLY BAY. How did you come up with the idea? What inspired it?
BITTERFLY BAY is a fantastical middle grade horror about a group of kid ghosts who haunt a lakeside cabin. They have (perhaps too much) fun freaking out vacationers . . . until something starts haunting them right back. It’s about bravery, storytelling, and the importance of facing the truth, and it’s got MANY weird creatures!
It was inspired by an old cottage my family used to stay at when I was little. I have so many fond memories of that place, but it was built right into a sheer mountainside and surrounded by dark, dense woods. (It also smelled a bit strange and had several creepy carved birds inside). BITTERFLY BAY came from those summertime memories of somewhere strange, comforting, and also super eerie.
2. What books did you like to read when you were a kid? Did those books influence your writing?
I was actually more of a fantasy than a horror reader! I loved Prophecy of the Stones by Flavia Bujour, The Two Princesses of Bamarre by Gail Carson Levine, The Land of Elyon by Patrick Carmen . . . so many! Even now, I still write my books with a strong fantastical element. I like blurring the line between horror and fantasy.

3. What are you working on now?
I’m revising another middle grade horror with my editor (shhhh, it’s a secret). I can’t say much yet, but it’s about anger and monsters and belonging and, y’know, fire powers. I’m excited to share more soon!
4. What was the most fun thing about writing THE GHOSTS OF BITTERFLY BAY?
I loved thinking up shenanigans for the ghosts’ haunting games! If I was a 12-year-old ghost trying to scare people, what would I do? It was fun to imagine haunting as a game rather than something terrifying . . . but it was also fun writing Longfingers and a more sinister kind of haunting, too.
5. What’s your favorite Halloween costume you’ve ever worn?
When I was five, I dressed up as Barbie Girl. (My title). Pink shiny wig, pink shiny dress, rhinestone wand, plastic high heels, and probably some fairy wings to boot. Not spooky, not scary, but I thought I looked SO cool. I always like sharing pictures of this one, because who’d have thought that twenty years later, this little Barbie Girl would get to publish ghost stories? Why not both?!
