The Cobra Trilogy is an epic piece of work, not only in size but also in scope. It leads the reader through multiple generations of Moreau family, visiting many planets and introducing dozens of characters who participate in the story as it develops, sometimes from one generation to the next. In classic Zahn style, even the smallest detail can later be instrumental to the plot, and the need for Deus ex Machina rarely if ever rises it's ugly head.
Despite the first of the three books being quilty in jumping a lot from place to place, the reader rarely feels like he's missed something vital. Fortunately, this jumping virtually ceases by the second book, and is only used to skip the long, unimportant periods of mundanity so that the reader can quickly reach the next key event.
