A surprisingly philosophical book that brings many questions to mind and causes a change in perception of the very world. The world of three species was an intriguing surprise for the Enterprise crew and the reader. The amount of creativity shown by the author through the very creation and fleshing out of such alien beings and thoughts was wonderful, the added time element positively mind-bending.
I in particular loved the switching of view as it pertained to being captain of a starship a wonderful look into the minds of the characters. The opportunity to read of Dr. McCoy in a command position so changed from his sickbay was beautiful.
