The novel “Ultima” by Stephen Baxter was published for the first time in 2014. It’s the second book in the Proxima series and follows “Proxima”.

A group of people reached a different timeline and only the artificial intelligence known as Earthshine has some idea about what’s going on. The human beings who made that strange journey are only interested in trying to make a living in the new conditions despite the difficulties.

For Earthshine the matter is quite different because its plans are much more ambitious and long-term. The new situation is just another step in the search for the mysterious creators of hatches and kernels. His actions, however, can bring unexpected consequences, at least for his old traveling companions.
