“Full review here: http://blog.butterflytempest.net/book-review-beautiful-darkness/
Thankfully, this book didn't suffer from second-novel syndrome. It answered questions that were raised in Beautiful Creatures, and raised some more to be answered in the next one. Ethan and the gang had themselves some adventures in Beautiful Darkness.
I appreciated the fact that the authors didn't just make Lena stay the same as she had been before after the events in the previous novel. Beautiful Darkness gave us a deeper look in to the pull of Light and Dark on Lena, and how she felt about having to choose to declare herself one of the other, particularly at the expense of half her family. It obviously affected her quite a lot, and the fact that she felt quite guilty about Macon, and what happened to Ethan as well, was very apparent.
There was a few things revealed about Ethan's mum, and about Macon that sort of come out of the blue for me, and I felt as confused as Ethan when we found out these things.
One of my favourite things about this was the Tunnels. They are like a characters within themselves really, and gave a 'Alice in Wonderland' feel to parts of the second half of Beautiful Darkness. ”
