The Strain on topic
The Strain is a 2009 vampire horror novel by Guillermo del Toro and Chuck Hogan. It is the first installment in The Strain Trilogy, and was followed by The Fall (2010) and The Night Eternal (2011). Del Toro first envisioned the story line as a television series, but was unable to find a buyer for the series. An agent then suggested turning the story into a series of books with writer Chuck Hogan. A television adaptation has been airing on FX since 2014.
