"I am Spock...I hold the rank of Commander in the Starfleet of the United Federation of Planets; I serve as First Officer of the Starship Enterprise. I am the son of two worlds. Of Earth, whose history is an open book...and of Vulcan, whose secrets have lain hidden beneath its burning sands...Until now..."
It is the twenty-third century. On the planet Vulcan, a crisis of unprecedented proportions has caused the convocation of the planet's ruling council - and summoned the USS Enterprise from halfway across the galaxy, to bring Vulcan's most famous son home in its hour of need. As Commander Spock, his father Sarek, and Captain James T. Kirk struggle to preserve the very future of the Federation, the innermost secrets of the planet Vulcan are laid before us, from its beginnings millions of years ago to its savage prehistory, from merciless tribal warfare to medieval court intrigue, from the exploration of space to the development of c'thia - the ruling ethic of logic.
And Spock - torn between his duty to Starfleet and the unbreakable ties that bind him to Vulcan - must find a way to reconcile both his own inner conflict and the external dilemma his planet faces...lest the Federation itself be ripped asunder.
