A Weapon of Magical Destruction

Sage Cynwrig knows her way around a pair of twenty-sided dice and has forgotten more spells than you'll ever know, but when her mother is killed by a weapon of magical destruction, fantasy merges into a bizarre version of reality.
Magic is no longer a game. It's real, deadly, and inescapable.
Her birthmark morphs into the Tree of Life. Then her boss goes full troll, warts and all. Don't even get her started on the playboy vampire who won't take 'no' for an answer. Oh, and she's pretty sure the shadows have come alive, and are stalking her in the darkness. Worst. Day. Ever!
Just when she thinks things can't get any weirder, some supernatural pick-up artist, claiming to work for the A.S.S.E.T. agency, tries to kill her. 
Why? Because some god gave her a mystical tattoo. Sage is a Terra, a race of people created by the gods to protect magic. Too bad no one bothered to teach her how to use her unique gifts. 
To catch her mother's killer and recover the WMD, she will have to accept her destiny as a Terra, preferably before she and magic as we know it are wiped from existence.
