Military-trained whiz kid June and Robin Hood-esque Day met in the first book, and now are off from Los Angeles to Sin City in Prodigy (G.P. Putnam's Sons), out in bookstores Jan. 29. The Elector Primo of the Republic has died, with his son assuming power over what's left of the USA's West Coast as it teeters on full-blown chaos. June and Day join up with Patriot rebels so they can rescue Day's brother and head east for the Colonies. In order to help, though, the rebels want June and Day to kill the new Elector, who may be a step up from his dad.
