Something like Recursion (B. crouch) or Project Hail Mary (A Weird) or The Road (C. McCarthy)

I'm going on holiday next week. The three titles mentioned above were on my tbr list, but they're not available in my library at the moment…

Suggest me something similar. Or a thriller with a very well constructed plot.

I'm also a very slow reader. So not too big of a book please 😁

Thanks!
