This book takes place about 2 years before the birth of Superman, a.k.a. Kal-el. We follow Jor-el and Lara (Kal-el's parents); Zor-el (brother to Jor-el); and General Zod, Aethyr and Nam-Ek (the main bad guys). It tells a story about people trying to survives through great crisis. I had not really read many comicbook-based novel, so this was new to me.
The flow of the book moves smoothly through each of the chapters, which are short but have a lot of action throughout. The characters are entertaining, the good guys likable and the bad unlikable in a likable sort of way. It was entertaining to see characters from movies and comic book react with each other, like an appearance of Brainac I wasn't expecting. I have not read many Superman comics, but in the ones I have read more recently, Superman tends to have a negative, "I am superior to all" ... I don't know, I actually prefer Batman. That said, I liked this book because it was not about Superman, but his family and where he came from, and thus where he's coming from.
I thought it was a little redundant to keep having all these catastrophes happen all at once, but I guess the action had to come from somewhere. There are many series I see clearly--like Jor-el creating the Phantom Zone and Lara saving him from it, which helped spark their romance.
I enjoyed this book a lot and will have my eyes out for more comicbook-based novels.
