Few elements of sci-fi really, more a life story of a mathematician in Sri Lanka. Some hard to believe stuff like Olympics on the Moon and Solar Sail racing as ways to encourage tourism... Not enough time spent with the aliens to my taste. ( )

La última novela (póstuma) de uno de los maestros más brillantes en el campo de la ciencia ficción (Arthur C. Clarke), escrita en colaboración con otro gran maestro del género (Frederik Pohl), aborda un mundo en el que tres grandes potencias, Estados Unidos, China y Europa, instaladas en una estabilidad muy precaria, se ven abocadas a una lucha por la supremacía pese a sus deseos de llegar a una paz. La amenaza más peligrosa, sin embargo, llega inesperadamente del exterior, y las investigaciones llevadas a cabo en secreto en búsqueda de un arma definitiva deben entonces reorientarse ante esa agresión exterior, que quizá sea lo único capaz de unirlos en un proyecto común. Mediante la historia de un joven astrónomo y matemático superdotado, Ranjit Subramanian, obsesionado con un teorema que parece encerrar los secretos del universo, Clarke y Pohl desarrollan una estremecedora y subyugante visión acerca de lo que el futuro depara a la humanidad, que nos induce a reflexionar sobre los cauces que debería tomar la colaboración entre Estados.

This was an interesting piece of fiction which managed to meander around plot lines without really settling on one. Little was extraneous (for every time I said "why did they tell us that?" I later said "ah, that's why"), but much was contrived. An interesting read if you want to read reflections on society, life, science, and technology woven into a narrative form, but not necessarily a good story. ( )

Really a 4.5 if I could have given it. Great book with loads of ideas being just tossed around for you to notice on the way past. It does feel a bit like the two of them have just thrown everything into this and there's bits that seem a bit more "adventure yarn" than classic Clarke, so I'm guessing that must be Pohl's influence as I've not read much of his work. Anyway, definitely worth a read. ( )

Given the pedigree of the two authors, I was expecting a lot more from this book. I just couldn't buy into the whole "world-famous mathematician whose childhood best friend is a major UN figure and whose daughter is a world class athlete and whose niece (or cousin, or something; I'm not entirely sure) is a world class doctor" mode of moving the plot forward.
