Would've been a four star as I found the book fairly engaging, but the end annoyed me. Claire Elliot is the main character, we see most of the book through her eyes, she is the key figure pushing for answers. And yet at the end of book (minor spoilers about how the end is handled rather than story specifics)

Spoiler

a man is given the answers and thinking about them, rather than her? She will just presumably find out the whole answers to the mystery at some other point when she's had a little rest? Indeed even the final paragraphs are given to the man in question!

It felt rather rushed, which was a shame as it was quite enjoyable if not super exceptional up to that point.
