The follow up novel to [Harry Turtledove's] [Supervolcano: Eruption] was worth the read. The continuing story of the characters as they try in their own ways to survive was enjoyable.
[Supervolcano: All Fall Down] picked up right where [Eruption] left off. In the midst of this disaster the way [Turtledove] portrays his characters not as hero's out to save the world but as humans with all their faults makes the story more believable. It even has a serial killer mystery twist within the plot.
I definitely prefer my science fiction based on real science and not super natural. That is what [Turtledove] has produced so far with the two books from the [Supervolcano] series. I like my fantasy with a good does of reality in most cases.
