Orthogonal (novel)
Orthogonal is a science fiction trilogy by Australian author Greg Egan taking place in a universe where, rather than three dimensions of space and one of time, there are four fundamentally identical dimensions.[1]
Technically, the space-time of the universe portrayed in the novels has a positive-definite Riemannian metric, rather than a pseudo-Riemannian metric, which is the kind that describes our own universe.
The first novel of the trilogy, The Clockwork Rocket, was published in 2011,[2] the second, The Eternal Flame, in 2012,[3] and the third, The Arrows of Time, in 2013.[4]
