This young adult thriller is the sequel to Day Zero. The cast of characters is pretty much the same group as in the first book. The action is told from the viewpoints of two teenaged stepsisters, computer whiz Susan (Jinx) Marshall and the budding journalist MacKenna Novak. Jinx’s dad, Maxwell, was a computer science professor who taught her well. He had a pessimistic view of society, wrote a survivalist handbook, and conducted drills with his family and with students to prepare them for an inevitable doomsday. The political climate in the US grew intense, with a severe economic depression and division between the adherents of the two competing parties, The Spark and The Opposition. Maxwell supported The Opposition, until he suddenly didn’t anymore. Jinx’s mom, Stephanie, a high school history teacher, was ostensibly for The Spark, and eventually divorced Maxwell and married MacKenna’s father, widower and bank security officer Jay Novak. MacKenna’s college student brother, Toby, and Jinx’s younger brother, Charles, complete the blended family. Other characters introduced in the first book come back in the second book as well, and there are a few newbies.
Day One begins about a month after Day Zero ends. DeVos does a good job of setting up the background for the reader, but I don’t want to go into it here, because Day Zero is so good, you should read it first, rather than me spoiling it for you by giving you a quick summary. Let’s just say that a crisis occurred in Day Zero that paralyzed the country, and it became very dangerous for everyone connected with either Maxwell Marshall or Jay Novak (so, basically, the entire family is in mortal danger). A major plot twist at the end of Day Zero shattered the family. Oh, and in Day One civil war breaks out.
Every character has a different goal. Finding Charles, who’s been kidnapped. Proving Jay is innocent of espionage. And preventing a cold fusion bomb from being launched. Sometimes Jinx and MacKenna work together, and sometimes they separate and work at cross purposes, but they and the others all believe they are following their best (and only) possible courses of action. Nothing is as it seems, and nothing goes according to plan.
Day One had me in anxiety all the way through. I identified strongly with Jinx and MacKenna, who, although they don’t always agree, are very idealistic and passionate about doing the right thing. As in the first book, there are multiple plot twists. Every chapter ends on a reversal or a surprise. The pace is rapid, requiring split second decisions of the characters, often without knowing all the facts. The book ends with the three goals being accomplished, but the country is still at war, and a sizable percentage of the characters are dead. I feel that the ending is realistic and satisfying, though not rosy. Day Zero and Day One are both excellent books, well worth reading. Just try not to see all the similarities to our present political situation; it could freak you out.
