I think it involved a child genius inventing time travel with something that looked like salt and pepper shakers because his family was being targeted by an assassin for some reason

Also might have been a fever dream not sure

It's called From the Corner of His Eye. He's not time traveling, he just figured out how to hop between different alternate realities. It happens to be one of my favourite books.

Ive been trying to figure this out all day and thats not it

Im pretty sure ive conflated parts of Mr murder and a completely different author/book called the mark of the assassin and honestly maybe parts of a 3rd book i havent remembered yet

I read those ~15 years ago

Well then that's a weird coincidence because From the Corner of His Eye is about a child genius who can move between different realities and is being targeted by a serial killer.
