Disaster Survival

When a coastal town is cut off after a megatsunami and the radio goes dark, a rescue-swimmer and a retired engineer must interpret a repeating coded signal coming from beneath the flooded waterline before the next surge arrives.

When a fire-behavior analyst reads a wind shift that command refuses to believe, she must convince a mountain valley to flee the Ochre Fire before a pyrocumulonimbus turns the ridge into a blowtorch, and the cost of being right is everyone who waits for orders.
