TimescapeSuspense builds in this novel about scientists, physics, time travel, and saving the Earth. It's 1998, and a physicist in Cambridge, England, attempts to send a message backward in time. Earth is falling apart, and a government faction supports the project in hopes of diverting or avoiding the environmental disasters beginning to tear at the edges of civilization.
In Finney's wonderful cult classic Time and Again (1970), Manhattan adman Simon Morley joined a secret government time-travel project, transported himself back to the New York City of 1882, fell in love and decided to remain in the past. This entertaining sequel, which traces Simon's attempts to alter a course of events in 1912 and thereby prevent WWI, lacks the magic and urgency of its predecessor but is diverting nonetheless.
