Dreamfever by Karen Marie Moning
Quite an interesting turn of events for Mac in this one. In fact, we don't pick up from her point of view. Instead be get to see through the eyes of another sidhe-seer as Mac descends into madness. A good chunk of this book is Barrons trying to snap her out of it - but his methods are far from traditional. And while I applaud his originality and ability to stick with it for sooooo long, it was really soooooo long and I got a little sick of it. But that is just the first section of the book.
The walls are gone - no more - zip - nadda - gone, and both Seelie and Unseelie are roaming the world freely. This leads to some very big what the hell moments because things are seriously messed up. I really enjoyed seeing Mac explore this new world and adapt to it as things kept getting thrown her way.
This wasn't my favorite of the series - mostly because I want more fighting Mac and less, well, the Mac at the beginning of the book.
