Reasons that made me love this book and made me read the whole series multiple times: 
 1.	Jericho Barrons. 
 2.	Naughty, sexy V'lane. The death-by-sex Fae. 
 3.	Ireland and especially Dublin. 
 4.	The world building. The Fae. The Seelie and Unseelie. I haven't really decided which of them are the bad ones. 
 5.	The pubs in Dublin where you can meet monsters. 
 6.	BARRONS BOOKS & BAUBLES. The bookstore which stands between two worlds. I want to live there! 
 7.	The rainbow outfit. 
 8.	The Sinsar Dubh. Just the fact that A BOOK is the most powerful dangerous thing in the world, makes me happy. 
 9.	Have I mentioned Barrons? He is the first paranormal guy that I have had a huge crush on (There were others after him, of course...sorry). 
 10.	The writing style. I could not stop reading. 
 And there is this anticipation that something big is coming in the next books. 
 Just count the signs. 
 This series is a perfect example of how an urban fantasy series should look like.
