Just returned from a difficult space mission and about to begin teaching at Starfleet Academy, Spock chooses a logical way to relieve stress: a sexual encounter with someone he'll never meet again. But when Spock discovers his partner of one night is Jim Kirk, a promising new cadet at Starfleet, he's torn between his rational decision to avoid intimate relationships and his increasing fascination with Jim. As Spock's normally orderly life starts to spin out of control, will his obsession with Jim prove his salvation or his undoing?
