The Gone World by Tom Sweterlisch

 

This is a kinda Weird--as well as weird--SF novel, layers of time travel and alternate futures wrapped in and around a vaguely Lovecraftian inevitable End. There's some serious implausibility around the premises, but it's distinctly baked-in, if you have those sorts of problems this probably isn't a great novel for you. I didn't exactly have novel-breaking problems with it, but continuing suspension of disbelief was a conscious choice. The prose is probably a notch or three on the plus side of functional, the characters manage to remain consistently themselves even when they are different iterations of themselves, the story is complex and convoluted but manages to be reasonably clear for all-a-that. A reasonably good read, if not a great one.
