Valek is determined to protect Yelena, but he's quickly running out of options. The Commander suspects that his loyalties are divided, and he's been keeping secrets from Valek...secrets that put him, Yelena and all their friends in terrible danger. As they uncover the various layers of the Commander's mysterious plans, they realize it's far more sinister that they could have ever imagined.
Valek certainly goes through several transformations and trials in Night Study and I was amazed at how adaptable he became.
One thing I wasn't necessarily expecting, but was pleasantly surprised by, was the romance. We all know Yelena has a way of bringing out Valek's softer side, but there are a few really sweet and touching moments, where Valek really gets his romance on... This being said, you really wouldn't want to cross the guy or mess with Yelena!
I'm not going to discus the plot because I don't want to give anything away, but I will say the story took a few unexpected turns and I spent most of the book in a heightened state of Owen related paranoia.
It's always nice to catch up with Leif, Janco and Ari - they never fail to make me smile, but it was nice to meet some other fun new characters. I still have lots of questions as to where the story is going, but I'm really looking forward to Dawn Study - if only the wait wasn't so long...
