I love Rafe and Taro. They are easily in my top 10 of all fictional characters. KD Sargehas published her fifth book in the Dream'verse, and this is the third one that features Rafe and Taro as the central characters. Now that they're settled on BFR and settled in their relationship, it seems like things should be a bit easier, but a mysterious someone who's bent on revenge can complicate the most conventional relationship. And Rafe and Taro don't have one of those.
I've read and reread all four of the previous Dream'verse books, as well as KD's short stories--some available at Turtleduck Press and some through the M/M Romance group on Goodreads. (You must be a member, but that's free and so are the stories.) I've spent decades reading murder mysteries written by a wide variety of authors. You'd think, after all that, that it would be tricky to completely flabbergast me, but KD managed it. Even when I had a Very Bad Feeling™ about Taro going off on his own, I was utterly surprised by what actually happened. I love a mystery that can fool me.
