content: While I was initially intrigued by the premise behind this book---spaceship wandering aimlessly, with no "memory" of where it began, no purpose in its wandering---I was disappointed by the unanswered questions. So much more could have been revealed, which would have added a great deal of interest, not to mention satisfaction, in the last chapter. Who were the aliens? Why did they impale humans mercilessly? Why the elaborate ruse of the vessel if the goal was simply to murder humankind?This book was frustrating, to say the least. I don't recommend it unless the reader is accustomed to multiple unresolved issues.
