Janaya - Alien Encounter, #1

Book 1 in the Alien Encounter series. Janaya is a bodyguard on a mission. She must protect her Aunt Hinekiri from mercenaries and return to Dalcon in time to take her captain's exam. A simple assignment for an officer of her caliber-except nothing goes as planned. Their spaceship crash-lands on Earth. No spare parts available. Big problem. Janaya is stuck on a tiny outpost called New Zealand. She's going to bungle her promotion chances.
And because she neglected to have her travel inoculations in her urgent hurry to protect her aunt, Janaya has bonded with an Earthman. Police officer Luke Morgan seeks a quiet life. No press. No nosy reporters. No women. Just lots of fishing and fresh country air. He doesn't count on meeting a pair of aliens and a talking dog, or participating in a shootout with purple-suited aliens. Nor does he expect the surge of lust he experiences for Janaya.
Suddenly a routine callout turns into a huge problem that Luke suspects might only be the tip of the iceberg.
