Books like Gilda Joyce: The Ladies of the Lake

The book is about a girl named Gilda Joyce who is very intelligent and is trying to solve a mystery about a girl who has gone missing and who made her disappear this story is a mystery which in this case a few of the girls at her new school while she is investigating this disappearance she is also a writer at her house writing down her stories.I like this book because I like how you can't stop reading it and the mystery just gets more confusing which makes it better because you want to know who made that girl disappear and who was that girl that disappeared
