In my opinion this book is nothing less than fantastic. It consists of various stories that feature different characters and it's all based on different vessels that had the name Enterprise, starting with a sailing ship during the American War of Independence.
Each story focuses on the captain of that ship at the time. Captain Harrison from the movie is there , then captains April, Pike, Kirk and Decker from the starships, followed by more captains.
The Captain April story involves Kirk and a major villain from Kir's past. Mc Coy is invovled in one story along with other stories involving Doctor Chapel, V'Ger, Captain Spock, Saavik, a really neat story involving the holosuite and a story about Captain Picard and the Enterprise D.
I felt that each story deserved a five, they were that good. A thoroughly enjoyable novel.
