Only one from your list I have read is Piranesi, but I just had to say I really enjoyed it. I'm a big fan of the genre so it was admittedly right up my street.
Some titles from my 'Short' TBR list include
- The Tusks of Extinction by Ray Nayler after really enjoying The Mountain in the Sea.
- The Long Mars by Terry Pratchett and Stephen Baxter (#3 in the Long Earth Series).
In terms of waiting I only have a couple
- Doors of Stone by Patrick Rothfuss... But by now I should probably reread the first two once it is actually out.
- The Martian Contingency by Mary Robinette Kowal (#4 in the Lady Astronaut series).
Edit: removing a spoiler that didn't get redacted properly.
I listened to the audiobook from Audible (GBP £8 ~ US $10) and would definitely say it was worth it. However, I understand the differences between the Martian and PHM can be divisive, but I loved it.
