Babylon 5 : Deadly Relations : Bester Ascendant
by J. Gregory Keyes

Description:
Born in the fire and terror of the twenty-second century, the Psi Corps--a group of elite telepaths used to control their own kind--became a finely tuned instrument of oppression. Only the underground, under the determined leadership of Matthew and Fiona Dexter, held out any hope for freedom.

But in 2190, the underground was shattered. The Dexters were killed, and their only son--the brightest hope for the future--was claimed by Psi Corps. To sever all connection with the past, the child was given a new name: Al Bester. From that moment forth, to Bester, "the Corps was mother, the Corps was father."

ester was a telepath of exceptional ability. Ambition drove him to be Psi Corps' most ruthless operative and to seek to become its master. To attain that goal, he would pay any price, betraying love, friendshipm ad humanity. And one day he would step into the void beyond death, to confront his own soul--or what remained of it. . .
