A message from space discovered by a SETI researcher's grandson, it speaks of doom for humankind. Twins flung through the reaches of time, their parallel lives mirroring more than looks and genetics. An alien armada spotted in the deepest reaches of the solar system-and headed directly for Earth. A tormented writer so close to revenge he can practically pen the ending himself and finally put his demons to rest. These stories and more await within the pages of by R.F. Walden. While known mostly for his climate fiction (cli-fi, as they say in the industry), R.F. Walden also writes science fiction that seeks to examine humanity's choices through the critical lens of environmental impact.
