I was waiting for this book and I can say that it didn't let me down. Just like the first book, it was thrilling and I was always excited to turn to the next page. The only problem is that there were many typos in the book. But still, that isn't enough to change my opinion.
I recommend this book if you're fond of mysteries (actually meron pa akong mga tanong na hindi nasasagot kaya babasahin ko ulit. Matagal din kasi ung gap ng pagbasa ko sa first book at nung sa second book). And you should be able to handle gore or brutal scenes, since there's a lot in this book.
Basta, kung nabasa mo na yung first book, basahin mo na agad yung second para hindi mawala sa isipan mo yung details at POVs ng mga character.
