[cwozii]

hello everyone! im trying to find a book that i first came across in a recommendations video on booktube but i don't remember the title and i can't find the video as well


the book where the characters are in a bookclub and they receive an anonymous invitation to an abandoned island where i think a murder took place some years back so they think they'll investigate it and then write about it in their magazine i believe. but some of the members think that this is too shady so some of them stay behind and others go to the island. after they leave for the island, the ones who stayed behind start receiving anonymous letters so they think there is a connection with the invitation and the letters so they start investigating these letters

zzi, I moved your request to the "Unsolved" folder because you're looking for one specific book.

How old are the main characters? Is this book for adults? YA = teens, in this group.

Around what year did you first see this book?

[cwozii]

the characters are in high school.
i came across this book in a youtube book recs video two months ago, although i don't know what year it was published in
