The Camp Fire grew to disastrous proportions faster than some fire experts thought possible, and ultimately destroyed the town of Paradise and devastated several nearby communities. At least 85 people were killed, and tens of thousands were displaced. In the new book “Fire in Paradise: An American Tragedy,” two journalists with the Guardian US, Alastair Gee and Dani Anguiano, tell the stories of those who were affected, from the early hours before the fire took hold to the months of uncertainty in the aftermath. But while the ferocity of this fire came as a shock, it’s unlikely to be California’s last such megafire.
