Child of the Fall

China was fun. For certain values of fun. Kim got to see the sights, taste the food, meet Mike's sister--his AI sister--and prevent a thermonuclear war. You know, standard touristy stuff.Now all she wants is to be a locksmith. Live the quiet life. Maybe join the Lions Club or the Chamber of Commerce or whatever it is legitimate business people do in their spare time. She's heard about those. They sound nice. But then her worst enemy breaks into her shop and tells her about a bomb. Mike's sister just called him about the same thing. The bomb is big enough to bury half a continent under a hundred feet of ash, sending the rest of the world crashing into a new ice age. But it gets better. The bomb is also the biggest clean energy project in human history. Everyone loves it. And only Kim can stop it.
