 Jackie smuggles Sydney out of the Moroi compound with magic by turning Sydney into a cat! So cool and sneaky. They're on a mission to go and save Jill after someone sent them a mysterious box with clues to where she's being hidden. 
 Hidden letters and messages leading them from place to place on a mysterious scavenger hunt. 
 First stop: A robot museum field with mutant fireflies that attack them. 
 Second stop: Ha ha Tonka mansion in the Ozarks of Missouri where they discover (assume?) Alicia is the one behind all this madness. 
 Third stop: Back to Palm Springs where it all began! 
 Meanwhile, Adrian is helping Nina find her sister Olive who has run away and learned to control spirit dreams in order to keep her sister away. They learn she's pregnant after breaking through her barrier and a "guest" and some damphir camp currently. Though breaking through that barrier cost Nina her sanity after wielding so much spirit power. 
 Oh my gosh technically Adrian and Dimitri are COUSINS ?! Plot twist. Adrian happens to run into his uncle - fathers big brother - in the town Olive is hiding out in only for Adrian to be harassed by him and Dimitri to sock him in the face. Strigoi attack the camp during Olive's labor only for her to be killed while giving birth. She tells Adrian during her dying breathe that the baby is damphir plus damphir which is unheard of! Sydney and Adrian take the role of parents to the baby until they can meet up with Neil (the daddy). 
 They have a run in with Alicia finally only to find out she does have Jill and she's being held captive (potentially) by the Warriors of Light. The plan is then to sneak Sydney and Eddie in to rescue Jill as recruits to be warriors of light. They end up saving Jill and in the end taking the role of Olive's son - Declan - parents because fear of him turning into a science experiment :) So so cute ! Yay for happy endings (hide spoiler)] 
 This book went full circle and brought back SO many beloved characters from The Vampire Academy original series and tied them together lovingly with The Bloodlines series. I was afraid I'd have to re-read the book before this or a lot of summaries because it had been so long since I'd read it. The author - as always - did a great job though refreshing me like she'd know we'd need it for a few of the characters. 
 I feel as though some of the plots could've been more detailed and "harder" though. Such as dealing with Alicia, the warriors of light, and the great rescue. I read this book SUPER fast and feel as though so much more could've been added to it in details. 
 Overall great series and great read :) I've read nearly every one of Richelle Mead's series and have no regrets.
