Currently, I have the following books on my wish list that I am thinking about buying.
Salvation by Peter Hamilton. I have read everything he has published except his short stories and love them so this is next on my to-read list.
Soon I Will Be Invincible by Austin Grossman. Seems kinda cool.
Seven Deadly Wonders by Matthew Reilly. It seems like a book in a similar vein as Jurassic Park, Dan Brown, Clive Cussler type stuff.
Pernasi By Susanna Clarke. I read her first book nearly 20 years ago and thought it was good. I really like creative sci-fi stuff. I am re-reading the Ninefox Gambit series again currently so this seems right up my alley.
Brandon Sanderson Way of Kings Book 3. Yeah, I probably need to start with Book 1 again and catch up. Has anyone read his Secret Books yet?
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.
