The 5th novel in the Moral Instruments series was my least favorite by far. I don't feel that anything really interesting happened in this entry into the trials and tribulations of the young Shadowhunters, aside from a lot of hooking up. 
 Slightly spoilerish: Maia and Jordan finally got together (yay!), but in a rushed manner that was unsatisfying to read, Simon and Izzy were adorable when they admitted their feelings (double yay!), but Alec and Magnus self destructed (noooooo!). 
 My biggest problem with the book was the fact that throughout most of the novel, I really wanted to slap Clary. 
 Rather spoilery: Clary's blind dedication to Jace should have been admirable, but her tendency to ignore everything and everyone else- including Luke's life-threatened medical status- really struck me as immature and self-centered. I also find it super-creepy that the series is still on the incest kick. Now that Clary and Jace know they're not related, she still has weirdness going on with her biological brother. She keeps mistaking Sebastian for Jace and Sebastian kept dancing on the edge of flirting before fully admitting that he wants her and will have her- sibling bond or no. Gross. 
 I hope that my Mortal Instruments binge reading has not gone too far- I was going to read the final book next, but I think I might need a little break before jumping into that world again.
