I enjoyed reading this book. Part One, starts at the top of the I-Fell Tower (the MC's nickname for the Eiffel Tower) with the main character, Shai, getting ready to fall with thirty-seven days, twenty-two hours, forty-four minutes, and seven seconds of her life left.
In this proposed future, adults are all in "the program". As a Recollector, Shai (and those like her) was designed to gather memories for Osiris, a "program". Recollectors can also visit in a "thread", a part of Osiris, while their bodies remain "topside". And, for most of her adult life, she has been trying to find a way to break out of the program.
She decides to visit the Cotton Club during the 1920s believing there might be an exit there. But, she realizes Osiris' deputies are there, too.
Part Two is after Shai has found an exit point. At this point, the story seemed to lag for me. I almost stopped reading. But, I'm glad I kept reading and pushed through because it gets better. Much better! I recommend this book if you like dystopian sci-fi.
I received an ebook copy of this book for my honest opinion and review.
