Other Time power like Clairvoyance (see the future), Speed up / Slow down, Stop / Rewind Time are nice too.
If the Time Travel power/device is unique, it must belong to the Main or Secondary Character.
I am not looking for novel with a single Second Chance.
(Loop or Multiple Chances like GroundHog's Day or Re:Zero is acceptable)
IMProvised Combat by Zenlith has a time mechanic http://royalroadl.com/fiction/3974
Frozen in Time (also by Zenlith) has a large time jump rather than any time mechanic. http://royalroadl.com/fiction/2920
I brought it to RRL largely thanks to k-fish's recommendation, but didn't want to post on the one-year-old message to say so. I feel better doing it on what is now a one-month-old message. :)
The main character starts by using a time machine, and eventually gains time powers herself. The story is now complete, though I am working on a sequel, which is why it has HIATUS status. One reason why I'm not around much lately. Anyway, pardon the self-indulgence, keep on time travelling!
has time travel elements, and even more than that. But since it's also based on the mystery of how exactly it happens, it takes some chapters to read before understanding what's truly going on. If a novel size story doesn't bother you, then I think you might like it. :)
