Exciting, but not consistently

In the game with subjective perception, pretensions of an indifferent or malevolent life world and the feelings of the protagonists of the novel to me Stanislav Lem reminded "Solaris".
I read the book in a few hours, because the built-up tension from the first page to was different almost unbearable. The basic idea pleases me well, as the Implied backstory of the main character and their character are internally consistent. The language reflects the scientific way of thinking of the narrative figure.
What I did not like, was the climax of the drama; there was me too banal, perhaps too obvious.
For the next two volumes I have my suspicions, in which direction it goes, and will certainly continue reading.
