Really enjoyed Unleashed. Secret is sent to California to represent Sig in dealing with a vampire from his line that might have gone rogue. She takes Holden and Ingrid along as her entourage. The missing vampire investigation leads them to the Winchester mansion in San Jose and into the clutches of a very dark sociopath. Several revelations in this book about Secret, Sig and the men in her life. Lots of action and snark, but very gruesome and tough to get thru at times. Still one of my favorite series.
