This book is not for ordinary sci-fi reader. With many physics theory and hypothesis and about multiple timelines, this book rely heavily on technical terms. The plot is confusing, the character development also felt neglected.
At first it was intriguing, to know the background story of the scientist, Tim Smith, who experienced tragic yet cliche tragedy involving his family, but the story itself quickly moved on to how Tim ends up in an asylum then visiting several alternative timelines.
If you are into quantum physics or other physics theorema then this book is for you. But if you, like me, a just-for-fun science fiction reader then you may pass this book.
Thank you netgalley for providing the arc in exchange for honest review.
