I recently read The Fall the second book in the vampire trilogy. I noticed it at the library and picked it up.
It was a good book. A very fast paced read. This story picks up where The Strain left off with the same principals Setrakian, Fet, Ephraim, Gus, Nora, and Eph's son Zack; battling it out against the Master, Palmer, and the Master's fast growing horde of turned vampires including Zack's mother Kelly.
Only one significant character is added in this book, an aged former wrestler named Angel who appropriately fought as the Silver Angel. In the story there are a number of struggles going on. There is a battle over a key ancient text called Occido Lumen that may hold the key to defeat the Master. Additionally there is the New York and now worldwide struggle against the spreading plague of vampirism, as well Eph and vampire Kelly battle over Zack's fate.
For a middle book the authors do a great job of moving the story along very swiftly while sticking to the storyline. There is the expected amount of attrition along the way to be believable. There are still enough principals left at the end of book two to make book three The Night Eternal compelling. I'll definitely read it when I see it.
