Encounter at Shalana - Adventures of Kristy Ryan, #1

Space pirate Captain Kristy Ryan grew up the only daughter of a notorious privateer in the Border Planet Region. She learned her trade the hard way - there were no free rides on her father's ship. Now, she has her own ship, the Unicorn, and successfully works in the shadows, the fringes of legitimate trade. Her life is just how she wants it even on those days when her pilot and lover, Andrew Bennet, drives her crazy.
But an unexpected visit from the Military Space Alliance changes everything. Her father disappeared while working a dangerous mission for the MSA. Now, she's being blackmailed into finishing his mission.
