I apologize if I posted this before (I think it may have not posted)

I saw this book in Barnes and Noble in 2017/2018. The cover has gold lettering and a garden on it. Female young adult main MC- tries to solve the mystery of why her sisters boyfriends keep going missing in their garden. Setting is current, possibly in England or Canada, somewhere gardens are popular.

Nora, how old is the main character? (This is your only request in this group. Here's a quick link to all your comments - https://www.goodreads.com/group/185-w...)

What's the genre (which we need to add to the topic header) - e.g., YA [teen] or adult mystery, thriller? Any romance or fantasy?
