A late addition to my Star Trek: Beyond series. It rightfully belongs between "Royalty" and "Angels in the Trees".

Spock and T'Naisa meet their match in this sometimes humorous, sometimes naughty adventure back in time. Their traveling companions, from a Trek series by Carol Johnson, have been shaped by their own unique circumstances. From Hollywood to Philadelphia, the displaced foursome must find a way to survive and ultimately find their way home.

After proving himself in a pitched battle, Commander Tobias Deacon is given command of the Yorktown-Class U.S.S. Challenger. On his very first mission as Commanding Officer, Deacon must come to the aid of an agricultural colony who are experienced inexplicable geological instability.

As Deacon heads deep beneath the colony, he uncovers a secret kept hidden under the serene surface of the planet. A secret that now threatens thousands of innocent lives as well as the crew of the Challenger.
