The Trouble with Unicorns (Team Unicorn Talia #1‪)‬

Part-time demon tracker, full-time optimist …
Talia White does what comes naturally to a unicorn: Balances the scales between light and dark with hefty doses of love and joy.
Faced with a string of high profile demon possessions, Talia is determined to do her job, despite the fact that she finds herself strapped with a brooding dragon warrior as her new guardian.
That’s the trouble with unicorns … they’ll accomplish their goal one way or another, even if they have to get a little stabby to do it.
