Undiscovered Planet A Star Trek Spock Fan fiction

In the after math of Into Darkness, Kirk, Spock and the rest of the Enterprise crew are sent on a mission to investigate signs of life on an uninhabited planet near the Klingon territory. What the crew comes to discover is not civilization as they had originally thought, but a girl (Ellysa) left abandoned and in search of her missing family. As her mystery unfolds, the crew soon learns of an undiscovered alien civilization, a hidden planet, and new a threat to Starfleet and the United Federation of Planets. Ellysa is completely emotional, dangerous and illogical, yet, Spock begins to find himself drawn to her unfounded sensitivity. Will Ellysa ever find out where she came from?

He studied the curves of her round face, the pink tint to her pale skin, the tears that streamed like rivers down her cheeks and her rosé colored lips that formed a plump and dissatisfied pout. Her eyes, once a striking blue began to darken almost to an obsidian black and Spock could swear, he saw holographic flakes of silver and gold begin to form in them, reminding him of stars.

Ellysa found herself raising onto her tip toes and tried to push herself forward despite the men restraining her, she stared back at the Vulcan in rebellion.

"You are reckless, sensitive and naive-" Spock spit his words out bluntly, each one daggered her more and more. "You are all the makings of trouble. Logic puts that as a potential threat to this ship. That is what gives me the right to advise we rid of you. "

NOTE: This story takes place between into darkness and beyond. I obviously dont own star trek and I have made up Ellysa as an OC. I have also made up the alien race, made up 2 planets and a few creatures. These are not part of the Star Trek Universe.
