It's a kind of mix between "the invisible century" by Panek and a Murakami novel. Phylosophy and science, in fact, merge with a dreamlike dimension.
It's a nice story, the idea is intriguing; what Einstein would have thought and done if he had the opportunity to live in our time?
Not an easy topic, many questions are raised and few answers (perhaps too few) are given. The aim is to make the reader think. Not boring at all, possibly going deeper into each topic would have been dreary, but some things were worth a more in depth analysis.
A bit of inconsistency at some points. For example when the girl shows not to know even the basic physics principles, that is strange since she is an Einstein fan and chased for him for a long time.
