I just finished the first book in the Bloodlines series as an Addicted to YA January 2014 Book of the Month. I hadn't realized it was a spin-off of the Vampire Academy series, so the beginning was confusing since it seems to pick up right after the VA series ended. While I take it Rose was the central character in VA, Bloodlines focuses on Sydney Sage, an Alchemist who's in deep doo-doo for helping assist vampires (Moroi, not Strigoi) and dhampirs in the previous series. Yah, I was confused, too. 
 The good: Once this particular plotline took off, I found myself enjoying the role of supes in hiding at a high school. I am also intrigued by the Alchemists (science!). Also, tattoos with super powers. 
 The bad: I'm not a fan of the thin/skinny/diet angst presented (repetitively) as normal. And I hate Sydney's dad. Like a lot. 
 In the end, I'll likely read more in the series in the future.
