I like sci-fi. I like time travel. I like secret agents. The storyline in this book appeared to be right up my alley. 
 Kim Harrison seems to like to write brainless female leads. Unfortunately they drive me crazy. I started out really liking Rachel from the Hollows but intelligence leaked out her ears as the series progressed. I had high hopes for this "Peri". My dreams were quickly dashed when I realized that she is even dumber than Rachel! The premise of the book is that Peri is a military-trained time-traveller but loses her memory during every "trip" leaving her susceptible to brain-washing by her partner. Since she is a special snowflake everyone wants to control her, both the bad guys and the good guys. Kim's male lead, like in the Hollows, is pretty awesome. He tries to get Peri to trust him and (view spoiler)[ suggests a logical course of action to take down the bad guys but of course being the ditz that she is, she doesn't listen, comes up with an impulsive shoddy plan and gets captured easily, despite her supposedly excellent fighting skills. Rinse. Repeat. (hide spoiler)] I wanted to throw the book out the window. Luckily I was given a paper ARC so I didn't damage my eReader! 
 Kim's writing style for this series is very consistent with the Hollows - intricately described scenes involving all the senses and copious use of adjectives and adverbs. And then after all the pedantic description, a chapter ends and we skip weeks into the future! Many sentences start with the present participle. Since I can't quote from the book I'll make one up: "Brushing her curls back, Peri sipped at her steaming gourmet coffee with hazelnut double-pump and punched in the number for Silas on her glass phone." They start popping up often enough that they could form a trigger for a drinking game. How many hands does Peri have? 
 I would have given the book 4 stars for premise, but I have to deduct one star for whiney dialogue and one for an illogical plot with poorly developed characters.
