Kirk and Spock face their greatest crisis yet in a bold new Star Trek adventure!

Now Spock has been declared a traitor and condemned to the shame of the Federation’s highest security prison. And now Captain James Kirk must face the toughest decision of his command, while a lifelong friendship and the destiny of the free universe hang in the balance!
