When you first meet MacKayla, she's spending her day lounging around the pool, working on her tan. You can tell she's a girly-girl and takes pride in her appearance. Mac can be off-putting. She's about as deep as a 2 inch puddle. Until her sister is murdered. Against her parents' wishes, Mac travels to Dublin to find her sister's murderer. Not only does she have to face the horror of her sister's murder but also has to come to terms with what she is and that her life as a 22 year old Southern belle no longer exists.I loved Darkfever. And I loved Mac. I was hesitant about her being the heroine of this book because of how her character was portrayed at the beginning of the story. But in true heroine fashion, she realized she is important in destroying the Fae and that she needed to get it together and do what was needed to learn and train. There were moments of whining and complaining and of course, denial. It didn't last too long to the point of being annoying.  I loved Mac and Barrons' relationship. I'm glad that it didn't develop into a romance (yet) because I think it would have undermined the gravity of what they were up against. Barrons' sardonic comments regarding her appearance provided many laugh out loud moments. My favorite is when he referred to her outfit as a "perky rainbow."  I loved how he continually referred to her as "Ms. Lane." I kept waiting for the Superman reference but didn't get one. Maybe in the next book? The book ended with no real resolution. No tidy ending where everything is rainbows and sunshine. At first I kept pushing the next page button on my Kindle, thinking this surely can't be it! I'm looking forward to reading Book 2 - Bloodfever. I have plenty of time to get caught up on the series before Book 5 - Shadowfever - is released in December.
