By Andy Weir, Sci-fi.
As a result of a fairly plausible set of events, man is able to utilise anti-matter for space flight, and has a very strong motivation to do so (the imminent destruction of the sun).
He features a design of space rocket which changes the living space in two modes, either for accelerated motion or rotating to provide gravity when it is coasting.
The first thing it made me think about was and The relativistic rocket equation.
