I feel like Darkness, Be My Friend is the weakest novel so far in an otherwise excellent series. I would still recommend the series on a whole but I hope the next novels are better than this one. 
 Some people might not have a problem with it but for me there were some issues with the plot that were so far fetched that it had a negative effect on the believability of the entire series, and I already had to stretch my imagination to begin with so that's not a good thing. 
 Also there was a reference to an Alanis Morissette song and that's enough reason for me to lower my rating a little bit right there. I give this book three Ironic stars out of five.
