I've just come here looking for the same and I see you've had no replies. So here I am.
I'm going away at the end of summer and I'm already planning my holiday reads (and I've paid for extra luggage to make sure I can take allll of the books!).
So far, I've got Ann Patchett The Dutch House I've loved everything I've read of hers, so hopeful for this one.
I've also got a Maggie O'Farrell Instructions for a Heatwave based on the fact that I loved Hamnet and it was the first MOF I'd read, so fingers crossed.
I'm considering taking Bernadine Evaristo's Manifesto but I may read that before I go.
I think I'll buy lessons in chemistry too.
But that's as far as I've got. I may take some poetry, as it's my new obsession. Loving Liz Berry and her novel in verse, The Home Child looks great. But, although small, it's a hardback and I have a no hardback rule, having got a black eye the last time I read a HB and it fell on my face when I fell asleep reading it!
Does any of this help? I think I'd describe my reading preferences as highbrow-ish/literary-ish but not so highbrow it's inaccessible.
I also love a hyped-up book, the kind that's marmite, to see where I fall on the love-it/hate-it scale. Hated Eleanor Oliphant loved Hamnet!
