Another quick review of a book I read a long time ago, before I give it away. Humanity receives alien data, someone decodes it, builds a hypercube, and ends up connecting an overview of all humanity and the aliens or something. It was a long time ago. I think I read it on a flight. It was fine. A bit lack-lustre, kept me entertained for a few hours but without any need to chase down more by the same author.
