I got the ARC of this ages ago but never got round to it so thank you @BarbaraBB for bumping it up my TBR.
I loved it (read it in 2 hours) but it was totally not as expected from the blurb. That suggests it‘s a ghost story with a recently-deceased Max watching his girlfriend Hannah, but that‘s only a very minor part of this utterly fascinating novel.
It‘s quite a tough read though, covering past trauma and abuse amongst other difficult topics.
