'The Time Machine' is a timeless classic that will probably stay relevant forever. Well, unless maybe in like 800,000 years, when humanity stops caring about stuff like culture, science, and technology...
IF I may offer a suggestion or two .
Morlock Night by K W Jeter This is a sequel to The Time Machine in which the Morlocks have gotten control of the Time machine and have turned all of human history into their personal feeding ground.
Map of Time by Felix Palma This book stars out as one thing and becomes something else al together is a terrific book and very difficult to put down He wrote two sequels to Map Of The Sky and Map of Chaos neither of which rises a beat.
