 This book has the best and the most unforgettable birthday party. 
 It is Halloween day and it is Barron's birthday. 
 Mac appears to the bookstore with a big pink cake just for him. 
 Surprise! 
 Will he be happy and feel touched because someone remembered his birthday? 
 I don't think so... 
 Barrons does not like birthdays. He does not celebrate birthdays. He does not like surprises. He does not like big pink cakes. 
 "Never do that again, Ms. Lane. Do not insult me with your silly rituals, and idiotic platitudes. Never try to humanize me. Don't think we're the same, you and I. We're not." 
 This All Hallows' Eve will be memorable for the city of Dublin and for Earth in general. 
 The walls between worlds are shattered and Mac loses herself. 
 The book finishes with an epic cliffhanger and a seriously heartbreaking climax. 
 Where the hell was Barrons to save Mac? Where was V'lane? 
 Faefever is NOT a fairytale. It will bite you in the ass.
