He did this to me. No. It's way more fucked up than that. I did this to me.

I went in with zero knowledge of what this book was about and it blew my socks off. I was captivated by the book. I disrupted my routine for several days to read more than I typically would. This book could find itself get upgraded to five stars but for now it's a strong 4.5.

If you strip away all the trappings of personality and lifestyle, what are the core components that make me me?

I like playing with the thought of experiment of what would happen if you woke up with a clone. Would you set them to tasks around the house while you enjoyed your free time? Would you duel to be the only one?

My understanding of identity has been shattered...

Multiverse has been popularized in media over the years but Blake Crouch didn't assume what the reader knows, or doesn't. Complex theories are elegantly described and get slightly more layered and nuanced as the story picks up. I didn't find the hand holding patronizing and enjoyed how the intricacies of the science was casually inserted in the story.

Even with familiarity in the multiverse I still a shocked face when all successful Jason's continued to find Chicago prime and think they were the eligible Jason to resume the life they walked out on a month ago. I was so engaged with the story I didn't consider this being a possibility and enjoyed how this ramped up the climax of the story.

I can't help thinking that we're more than the sum total of choices, that all the paths we might have taken factor somehow into the math of our identity.

The story is rooted in science but offers plenty of "what if" questions that the reader can wonder about heavier questions like what makes us us.

The box isn't all that different from life. If you go in with fear, fear is what you'll find.

This was a fast paced, extremely engrossing story and will continue to think about it.

"And we're not lost."
We are fucking lost. Literally adrift in the space between universes.
"We're not lost."
