Roxy Buckles and the Flight of the Sparrow. The Adventures of Roxy Buckles, #1

Exterminator ROXY BUCKLES, a bounty hunter-cum-mercenary, lives on Aurora, a highly advanced Earth-2 planet in a solar system on the flip side of the Milky Way. At the helm of Buckles & Associates, Roxy takes down space thugs and alien lawbreakers with relish. Her longsuffering best friend, SUKI KWAN, runs the office with an iron fist. She desperately wants Roxy to let go of the past. But Roxy is consumed by a need for revenge.Ten years ago, Roxy's fiancé, SAM SPARROW, a high-ranking fly-guy at The Academy for Intergalactic Law Enforcement, stood accused of a heinous crime - setting a bomb that destroyed The Academy, killing hundreds of innocent people and leaving Suki Kwan with near fatal injuries.
Sparrow insisted his innocence but then he escaped custody, disappearing from the authorities' eyes. That day, Roxy swore she would bring him to justice, one way or another. Perhaps her time has finally come.
