Upgrade by Blake Crouch It’s a nice tight fast paced book. It suffers from the same problem all books about super intelligence have in that the main character just doesn’t feel all that smarter then everyone one else. But you can’t blame Crouch it’s really hard to write someone who’s mind is beyond our own. Martha Wells does a good job of it with Perihelion in Murderbot but their not the MC and we don’t spend time in their head.
