No one is quite sure who launched the app at first, but it is wildly successful.  Human women are as fascinated with alien warriors as warriors are with human women.  A system is set up so that they can match and meet, either on Earth or on neutral planets by mutual agreement.  Aside from a few minor incidents (dates going poorly, some xenophobia, a couple of people/ aliens going missing), it's a hit.

Anise, a young woman fresh out of college, gets signed up for the app by her meddling friends, and finds herself on a date with Silas, a dragon shifter warrior, who is unlike anyone she's ever met before. He's kind and thoughtful and considerate, and definitely the sort of person she could fall for. Too bad he's being hunted, and Anise is caught in the crossfire. Now Silas must protect himself and the woman he loves while hiding from his hunters. A seemingly impossible task….
