A science fantasy based on the supposition that texting messages from the future into the past changes universal cause-and-effect causing time to reorder itself. It ignores the existence of a universal reference - direction of space-time expansion - much like ignoring the speed of light for energy and time distributions. The plot is nonlinear and tends to unravel at moments into an interface of cliche. I expected the plot to follow a crystal structure based on its dimensional morphology. But then there wouldn't be much of a story if the future and present can not interact. Essentially if you are in a future timeline everything that happens is the past timeline. While if your timeline is in the future past (i.e. self referenced normal present timeline) future time is only accessible through your individual present timeline. ( Some S is P does not implicate All S is P) Just as the direction of gravitational acceleration depends on the direction of universal space-time expansion, universal causality is itself a linked property contingent upon this direction. Going back in time therefore is like playing a recording. There is no interaction with a self referenced present timeline. Mathematics is a proof of validity, not soundness. Bad physics, good fantasy.
