Ice Cold {A Modern AU LeviXOC Story}

Nikki Matthews is an undercover FBI sent to California from New York to find her missing adoptive brother Marco Bodt and her sister Adaline, who are also an agent. She's torn between being forced to do this. She doesn't want to lose it during interrogation and hurt the probable culprit, as she's short-tempered.
Then she meets Levi Ackerman, another FBI agent, who is still recovering to past trauma he experienced recently, and he's ice cold towards her.
And she is determined to break that ice.

This is my first LeviXOC story. Enjoy.
