I love, love, LOVE the Cirque Du Freak series and The Thin Executioner by Darren Shan. This book is the first in a four book series chronicling the life of Larten Crepsley (you know, pre Darren). I really liked Larten Crepsley throughout the Cirque Du Freak series so when I found out that there was going to be four books starring him that come before it I was so excited!
When I picked up "Birth of a Killer" I expected a book that was as good as the Cirque Du Freak series, probably similar, with Crepsley as the main character. This book was way more! I liked it better then I liked most of the Cirque Du Freak series. I'm not sure if this is because I like Crepsley better as the main character or if it is because Mr. Shan has developed more as an author since writing the Cirque Du Freak books, but whatever it is, it's great.
I liked seeing the beginning of what turned Crepsley into the great mentor and overall person in Darren's life. I thought the story was good with surprising turns, and new likeable characters. It was also really interesting to see Crepsley as the 'assistant' rather than Darren. Of course, there's also Darren Shan's amazing writing style which I enjoyed throughout the Cirque Du Freak books and The Thin Executioner before this.
I can't say much more without creating a rather spoiling review, but it was great! If you enjoyed other books by Darren Shan then you'll probably love this one as well! Also, the sequel, "Ocean of Blood" comes out this month!
