This was a great read! I adore the math and physics side of this nerdy sci-fi, and I enjoyed it enough to read it in a single sitting. My only complaint was that the final 10-15% of this book moved too quickly compared to the rest, making the ending feel somewhat rushed compared to the way the rest of the plot was laid out.
Once this book takes off, it never lets go. I devoured most of it in a single sitting because I had to know what happened next. It's mind-bending, fast-paced, and hits hard with its "what if" premise. It takes twists and turns that I didn't expect and kept me invested.
That being said, it has a slow start, a few awkward moments, and some lingering unanswered questions kept it just shy of 5 stars for me.
