Looking for a substantial literary novel to get lost in

[amoamas]

I have a very rare week to myself coming up, and I'd be grateful for recommendations for a nice thick book to take with me. I don't mind if it's a classic or contemporary fiction, maybe 400 pages or more so I can really get into it.

I have enjoyed: There are rivers in the sky by Elif Shafak, The safekeep by Yael van der Wouden, The hare with amber eyes by Edmund de Waal, Wolf Hall trilogy by Hilary Mantel, the Neapolitan Novels by Elena Ferrante, the Gormenghast series by Mervyn Peake, the Boudica series by Manda Scott, Shuggie Bain by Douglas Stuart, Orlando by Virginia Wolf. I've read most of the main classics but happy to explore some of the more unusual ones.

I don't enjoy: sci fi, "just" romance, very sad stories or anything that's unrelentingly grim, "light" reading (I want something to get lost in), politics.

Any recommendations gratefully received, TIA.

A Prayer For Owen Meany

Loved this book. Can't believe nobody recommended it earlier. It's so original, haunting and beautifully written.

Possession by AS Byatt
The Poisonwood Bible by Barbara Kingsolver
Wild Swans (i know Nonfiction but still epic)

Commenting so I don't lose the thread.
Echoing recommendations for Barbara Kingsolver and Daphne de Maurier.

Maybe doesn't quite fit the bill but I enjoyed the Book of Doors by Gareth Brown recently. I devoured it!

Just been using this thread to pick out a library haul so thank you all.

Cannot agree with A Little Life though. I hated it, relentless misery porn. Author creates someone unrealistically perfect and then has him horribly abused over hundreds of pages. Ugh.
