Basically the story is about Vegeta becoming a Super Saiyan during his fight against Frieza. Afterwards he takes over King Cold's empire and builds quite the reputation for himself. Vegeta's new found advantage inspires the others to train more (surpassing their Canon counter-parts), particularly Goku.
Goku still manages to keep up with Vegeta's growth and their rivalry is still alive and a major source of Vegeta's focus on training. This is one of the biggest strengths of the fan fiction. These are still the same characters despite what happened differently. While the heroes get stronger than their canon counter-parts, so do the threats. This keeps things interesting as the story progresses.
One weakness of this fan fiction is the clear bias against some characters (particularly Yamcha). Chapters also tend to linger a bit on figurative descriptions of the environment or a given character's thoughts. These moments tend to reek of unnecessary padding, especially jarring during cliffhangers. Personally, I would rather have multiple simplified chapter updates a week, than a single chapter where a third of the story is dedicated to a detailed description of Astronomy and theories of lightspeed movement.
Despite my criticisms, I would recommend this fan fiction to anyone who enjoys DBZ. The original flavor is still there but prepared differently.
