I don't typically read BDSM romance, but the author comes recommended by other readers and I found the premise of this book interesting, given the suspense angle. A detective in Hawaii is partnered with an FBI agent in a search for a serial killer tied to the BDSM scene. As you can expect - Detective Rome is involved in the Lifestyle and Agent Maria volunteers to immerse herself as his sub in order to bait their killer. I won't spoil the story, but I will say I found Schroeder's execution quite believable and compelling. This is the sixth book in a series, though it's written in a way that you don't feel lost or out of the loop when past stories are referenced. Time permitting, I'll have to check out another story from Schroeder.
