Thanks for the e-ARC, @harperperennial, in exchange for an honest review!
Whenever I read a book, I get lost in the imagery painted by the author in the form of words. And even when I am not reading, I am day-dreaming--either about the book or about random things. I have always been a dreamer, getting lost in my own thoughts, painting pictures, in my mind, of a world far better.
When Victoria, stuck in a dry, loveless marriage which is often difficult to read about at times, falls for a guy she saw in a cafe just because he was reading the same book as hers, it made sense to me. But that's where the 'sense' of it ends. At least, for me.

Victoria is a unhappy woman, privileged but has no agency of her own, who fantasizes about a relationship with this 'dream man', and often gets lost in her dark thoughts wherein she almost always ends up killing her husband.

This book was supposed to read like a fever dream, but it was a weak attempt. The story was repetitive, monotonous, and I pushed myself to finish it. The characters were all one-dimensional and irritating. Both the plot and writing lacked a strong foundation. Only halfway through the book, something seemingly interesting starts taking place, but then it soon fizzles out, like a day-old opened can of beer. Even the ending seemed abrupt.

The words 'bookworm' and 'fiction merging into reality' are just terms to entice a reader, but I was just disappointed.
