It feels bit like a contemporary Coehlo. Kind of obvious from the start how it is going to end, so you're basically there just for the ride. But I guess some readers need this ride, and will perhaps enjoy it more than me who found it to be an average ok nice book, but nothing more.

A negative thing is that the author wants to kind of over-explain different things, not letting us get to use our own imagination, for instance of how the library in detail could work. As a reader, you do not always need long explanations of how things work, we can piece it together ourselves.
