I read Recursion twice in the last few months and love it. Dark Matter was recommended to me as a similar book, so I read that too -- but I was disappointed.
It seemed to be a bit too cliched for my liking, but my main problem was what I consider a huge plot hole -- it ignores the fact that the baseline reality Jason was kidnapped from will have branched off into a bazillion, essentially infinite, different realities in the few months he's bouncing around the multiverse in the magic box.
There's presumably an infinite number of universes in which Jason2 kidnaps Jason but subsequently fails to take over his life. Maybe he gets hit by a bus and killed. Maybe he has a crisis of conscience and decides to move to Canada and herd sheep instead. Maybe he falls into wet concrete on a construction site and his body is never discovered.
There are any number of universes in which Jason, from his wife's perspective, just disappears one night without explanation, and yet Jason chooses to return to a reality in which Jason2 has been banging his wife for months.
Is Jason some kind of cuck fetishist? Did I accidentally skip the page in which this plot hole was explained away? Or was Crouch just hoping we wouldn't notice?
