It's obvious from the very first page that "When Ravens Fall" is a first time effort. The book promises dark romance and violence, and at the end of the book I realized that it attempted to be more complex and more mindf*** that its actual execution.
I really had a hard time getting into the story, mostly because the author's writing lacks discipline and finesse and contains glaring traps amateur writers often fall into but is usually fixed in Creative Writing 101. It is clear the author has never had any training in writing, otherwise this book would not have spectacularly failed in too much telling and not at all showing. Let me put it this way: the novel feels like a B-movie made for TV, with awful acting and a script that was once promising.
The biggest problem is the characters are underdeveloped and are rife with overused tropes. So is the plotting, moving from one point to another with major scenarios and timelines covered in a matter of lines.
I think the author intended this book to be unpredictable and really dark, and maybe discuss some sociology along the way. However, given the lack of characters' complexity, dubious motivations and overall lack of insight on the author's part, the book spectacularly fails to accomplish this. The summary for the book (though in somewhat of a disarray) claims the book wants to examine "free will vs. destiny." I have no idea what this means, but I think perhaps the author meant to examine the age-old, nature vs. nurture problem, whether bad people are the way they are because of their upbringing or just how they were born. This is what the seriously screwed up Sean and average Rachel's relationship is supposed to show us. Though the book claims the author has studied psychology, I never saw and ounce of scientific or psychoanalytical insight in this book, most of the "observations" about killers and psychos made from popular conceptions misconceptions and "pop-psych" ideas of the human mind. Human psychology is extremely complex, and so are motivations behind some criminal behavior, something this book fails to communicate to the reader. (If anyone is interested in a good book about abusive young male leads, I strongly suggest Breathing Underwater.)
Anyway, the author should be lauded for her effort for trying something new and not write another Twilight ripoff, so plus one star for that.
