Geoffrey Girard did something a little bit different. He published two books that tell the same
story at the same time. One, Project
Cain, (already covered here)
told the story from the point of view of a teenage protagonist and was a YA
book. The second, Cain’s Blood,
tells the exact same story but this time from the point of view of an adult
protagonist and is clearly an adult book.
I read both books, primarily because I wanted to see how different they
were and just how gimmicky the whole thing was.
So the author actually does a fairly decent job of making
the two books distinctly different experiences. The scenarios, timelines, & events are all the same of course
but the two different characters have very different takes on things and each
is involved in parts of the story the other is unaware of. Additionally the adult version of the book
makes plain certain aspects of the story that were more glossed over in the YA
version. The entire experience then was
quite interesting.
