 Amy is in love with Alexander Banks though there is one problem: he isn't real. He's the hero- the dark, brooding, handsome vampire hunter-of the wildly popular vampire hunter trilogy. So, it's all good until one night it isn't because that's the night truth becomes stranger than fiction. That night, she meets a boy claiming to be Alexander Banks who also happened to save her from Vigo, the ruthless vampire that Alexander needs dead. Now, she has to make sure no more lives are lost because of Vigo. Still, even if secrets are exposed and danger lies with her, she has to wonder if her heart is at stake. 
 Vampire Stalker disappointed me- not that I had high expectations for it. My final and first impression left me wondering how Allison van Diepen's writing could be so shallow In fact; everything about the book was shallow. 
 The insta-love between Amy and Alex was so thinly fleshed out; it left a bad taste in my mouth. I understand the book is dedicated to people who have fallen in love with a character in a book but still, Van Diepen should have made the "chemistry" (and I put quotation marks because there is none) believable. She should have added layers; made it more complex. They were both fine by themselves but together...there is no words. If she made the love realistic, then the ending would not have been so predictable. (view spoiler)[Alex ends up staying in her world; just like a fairytale (hide spoiler)] 
 Besides the non-existent chemistry, the characters were so flat and boring, it made me cringe. There was no depth to them and they were all flat except for a few-which is another reason the ending was so predictable. They had virtually no struggle, no internal conflict they had to deal with themselves. They were all the cliched kind of characters and they had such a specific role to fill in. Boring, boring, and boring. 
 Even the theory on literary physics sounded boring and far-fetched that I had a hard time processing it. It didn't sound all that realistic, but wait there's more. Next, there was Vigo's equation of probabilities that supposedly allowed him to escape Alex. For this, I am at a loss of words. There was no need for that and it made my mind go WTF? . Then there was the police's acceptance of vampires and this is what threw me off- so unrealistic and unbelievable. 
 After all this, there is still something else that bothered me: Vigo. As I already mentioned before, the characters were two-dimensional. I was hoping otherwise for him but hey, I failed. As soon as Vigo made his appearance, I knew he was going to be the generic villain; no struggles, no layers. 
 For the record, though there were a few upsides. (view spoiler)[James, Alex's cousin and Hannah, Vigo's sister appear in our world (hide spoiler)] When that happened, I was thrilled because finally, we got some juice going on. Then there was the (view spoiler)[kidnapping; Vigo kidnapps Amy's little sister Chrissy (hide spoiler)]. That got the ball rolling but then the lousy ending happened. 
 Oh, well. A person can only hope.
