I’m saving it too (I was the same with Iain Banks, I saved Hydrogen Sonata for ages. No, it wasn’t his last novel but I had a sneaking suspicion that the Quarry wasn’t going to be very good)
Vurt, by Jeff Noon, is one of mine. It’s melancolic but absolutely beautiful. I think the Watchmaker of Filigree Street by Natasha Pulley just joined it. Neither are funny but that’s not what I look for in a comfort book, I don’t want to laugh while feeling down, I want to feel better about feeling down.
If you fancy exchanging your current emotions for a bit of frazzled rage you could try Harry’s Last Stand, but be warned you might end up blowing up a politician.
