The Gone World

Based in western Pennsylvania in 1997, Shannon Moss, a clandestine agent of the NCIS (Naval Criminal Investigative Service) is investigating a murder of a Navy SEAL's family. The SEAL was also an astronaut aboard the spaceship U.S.S. Libra, a ship assumed lost in “Deep Time.” Moss herself, seeks clues by traveling roughly 19 years into the future aboard these special ships seeking clues. When she returns, she returns to the same moment she left, but she's aged by however long she spent in the IFT (Inadmissable Future Trajectory) – she goes on multiple trips. This investigation turns up some very gory murder scenes, some serious violence, and some baffling weirdness caused by time-travel shenanigans. The story has some very cool SF ideas, but sometimes I found keeping track of who's who a little difficult. And wow, the author really puts his protagonist through the wringer. It's a bit bleak (an end-of-times scenario is also worked into the plot), but I was interested to see how it all plays out.
