I recommend Bloodfever. 
 Sweet Bloody Hell. :D 
 The gory twist of Mac's appetite with regards to fae is so, so good. Find the Sinsar Dubh. Locate the other fae relics. Kill Fae as needed. This is her reality now. No more Pink Mac. 
 Bloodfever was repetitive on the first half, if you look into Barrons-Mac violent tandem. Romance is moot, so let's resort to blood-and-guts aggressiveness! LOL. Anyway, the good part came when Mac finds herself in a tight spot (again). And who will come to her rescue when she's near death: Barrons or V'lane?... 
 That cave scene was so freaky, I loved it! It's disturbing yes, considering the effects on Mac, but oh, I would rather see her evolved than gone! 
 V'lane is still this arrogant Fae, and almost as arrogant as Barrons. If I focused more on the fae lore than on the characters, I could say that I really, really like how this sequel turned out. More stories on fae, but still nothing from Barrons. C'mon! 
 Mac is better here, although she is still a fashionista (substituting pink for black, right?). Haha! She still does not take sh*t from Barrons, but for goodness sake, if she listened to him rather than antagonize him, I think they would've accomplished more in searching for the Sinsar Dubh. 
 Bloodfever is right up my alley for a sequel. It kept me wanting more, more of this fae madness. And the bloody bit in the end is a major plus. :D
