How can a colony on Mars survive when the greatest danger on the planet is humanity itself. All contact is lost with the first human colony on Mars during a long, intense sandstorm. Satellite imagery of the aftermath shows extensive damage to the facility, and the fifty-four colonists who called it home are presumed dead. Three years later, a new mission sets down on the planet surface to investigate what remains of the derelict site.

Because even in the jolliest of seasons there's a world or two to save.

Where life as we know it is impossible, the real adventure begins. Venus is a hostile planet, covered by active volcanoes, but NASA launches an expedition to search for life there anyway.

Fortunately, the husband-and-wife team are well prepared for their adventure, with a state-of-the-art hydrofoil and the assistance of the native inhabitants.

The question is: Will he agree?

Saying I've had a crush on my best friend's older brother, Pax, most of my life is like saying the big bang was just an explosion. It's true, but I'm not sure that quite captures the essence of its true enormity. I don't think my advanced physics knowledge is going to help me figure this one out. But I think for once I'm okay with not knowing, as long as Pax and I don't know together.

Months after Inara leaves Serenity, Mal and the crew finally learn the reason for her sudden departure: She is dying of a terminal illness.
