17 May 2014: $1.99 on Kindle (Books 1 through 7 are all $1.99 today) 
 Eh. I liked it, but it wasn't even as good as the first one. And Murphy irritated me to no end. I'm honestly not sure I can get past the way she acted. Thankfully she's not the main character. 
 And I already have the 3rd book, so moving on soon...
