Super complex thriller/time travel combo book. It’s both really thinky and also a little... basic? I sort of knew where it was headed by not too far into it, but it was cool to see how it got there. And then there’s an epilogue that kind of knocks you on your ass. Neat! I enjoyed a world where there were possible futures and some interesting limitations places on time travel/time travelers. And space stuff but it’s mostly hand-waved away. This book was right at the outside limit of my tolerance for gore though, how much “pink mist” can I read about?
