The Fall of the House of West (2015)

Aurora West is on the verge of solving the mystery of her mother's death, but it's hard keeping her efforts a secret from her grieving father, the legendary monster-hunter Haggard West. Between her school work and her hours training and hunting with her dad, Aurora is hard-pressed to find time to be a secret sleuth. But she's nothing if not persistent.
What Aurora doesn't realize is that she's about to blow open a secret that may very well destroy what's left of her family...and, indeed, all of Arcopolis.
