In Earth, a group of scientists search for a runaway black-hole-like singularity working through the Earth's core and hope to find it before it destroys the planet. This novel has some flaws and it was quite a challenge to read, but its ambitious scope is truly impressive. It has a vast array of interesting human and non-human characters and it shows an uncannily accurate view of the future.

The book was published in 1990, but I wouldn't have guessed it if I hadn't known beforehand. Brin's details of everyday activities, such as using the Internet, reading books on an e-reader and sorting your waste for recycling, are not so far from today's reality. However, let's hope that his frightening portrayal of an unstable Earth struggling under the effects of rapid climate change won't come to pass.

I left this in a Little Library for another reader.
