Shadow Walker. Stormwalker, #3

The world falls from beneath me-literally-one winter night when I'm racing down the road on my beloved motorcycle. I tumble into a huge sinkhole, followed by the sheriff, who's doggedly chasing me. I find myself in a cavern covered with evil petroglyphs that are intent on killing me ... From that harrowing situation I go to another even more dire: A hotel inspector who seems bent on putting me out of business.
Add to this, my evil little sister has surfaced to tangle with me, and now Mick, my dragon boyfriend, is acting mysterious and scary. Only the magic mirror, my interfering grandmother, and my new cook seem to know what's going on, all of them telling me that Mick has been touched by shadows. I have to figure out what that means and wrest him free of dark forces before the Dragon Council stick their smoldering noses in and a new witch in town destroys everything I love.
