Titan is practically a planet in its own right, with a diameter similar to that of Mercury, methane rainstorms, organic soot, and ethane seas. The views from Titan’s Mayda outpost are spectacular, but all is not well at the moon’s remote science base.

In Radiation Hazard, Kaem and company are commercially developing “stade”, a piece of space-time that’s in stasis. Its phenomenal properties allow it to reflect all radiation, so when a nearby nuclear reactor undergoes a meltdown, the first thought is that stade might be used to limit the radioactivity from the accident. In Halting the Reaper, Kaem has been treated with gene therapy for the anemias that have made him so weak. In combination with his extraordinary memory, his newfound physical fitness is letting him perform at a high level in a karate class.
