Present Tense is the first novel of the three-part novel series entitled The Janus Gate.
The crew of the USS Enterprise is exploring the seemingly peaceful and uninhabited world of M-3107 when a bizarre and inexplicable transporter accident causes both Captain Kirk and Dr. McCoy to vanish completely. Transporter records show that the two men were transported somewhere, but the ultimate destination remains a mystery.
Now in command of the Enterprise, Spock dispatches a search-and-rescue team – consisting of Security Chief Giotto, Transporter Technician John Kyle, and Chief Helmsman Hikaru Sulu – on an urgent mission to recover the missing officers.
But then the rescue team disappears as well!
