The main character in this story is a now seventy-year-old astronaut named Nick. After some adventures in the past (and told in previous books that I will have to read), he bought a vineyard and now enjoys life with his lover Raissa, his daughter, his wife and her partner. An extended family that lives happily and peacefully.
The day of his 70th birthday Valentina (Raissa's former boss in a powerful and mysterious Russian group, RB, with which Nick had dealings previously) contacts him and blackmails him by asking to embark on a mission to Uranus or she will kill Nikolai, his and Raissa's son. Nick will start this new adventure together with his friend Vitali, a Russian astronaut and together they will embark on their old ship, the "Eve".
Meanwhile, Raissa leaves for Russia with the aim of finding her son Nikolai, using her old contacts.
This novel is an exciting mix of science fiction and spy story, with a touch of humor and suspense that will keep up the reader's attention. The two subplots are carried out alternately: on the one hand Nick's exciting journey and exploration of the moons of Uranus in search of Nikolai, on the other Raissa's dangerous investigations in a territory where the RB has eyes and ears everywhere and in which she will have to extricate hermself from blackmail, deception and armed men. Both Nick and Raissa are helped during their search by rather unique characters.
The end of the story is rather unexpected, the subplots are closed, but it is as if the author intends to resume it in a next book. At the end there is also a chapter with scientific information on Uranus and its satellites.
It's a fun reading, but I recommend reading up well and starting from the first book in which these characters appear.
