What's the Name of That Book??? discussion

I read this book perhaps 10 years ago? The cover might be sepia, or black and white.
I think MC moved to seaside town (possibly in England) and is young (I think a young girl). There is a mystery of a young girl who died many years earlier, but maybe people think that she survived and sailed away? The girl who died had an older brother, who I think might have been involved in her death in some way? Very vague memories about this book, but it has been bothering me for a while. I really associate the song "Sail Away Sweet Sister" by Queen with this book, it sort of captures the theme/feeling of it?

Mathilda, is this book for young adults (teens) or older adults?

What's the time period? Any references to technology?

Kris - I can’t really remember, I think it might be for older kids/teens (I was like 11 when I read it I think). As for technology, I have no idea, but I think the later perspective was like ”today” and the older perhaps 50 years ago or something, not older than 100.

Maybe Cold in Summer?

Holly - Thank you, it’s very similar, but it’s not the same from what I read in reviews and the synopsis.

The Ghost by the Sea by Eileen Dunlop?

Kym - Thank you! That’s the one!!!

You’re welcome Mathilda.
