I picked this up not knowing it was book 2 in a series, but they appear to be standalone (with one crossover character, from what I gathered). So I don't feel it's necessary to read It Came From Above before this book. This was a super fun cross between a survivor interview and found footage. Some of the dialogue came across a bit stilted at times, but it added to the whole B movie vibe of the book. I could definitely see it making a really fun found footage movie. I plan on checking out the rest of the series. 3.5 stars
