i've yet to read Pride and Prejudice of Zombies....but from what i understand its basically the entire Jane Austen book and he simply added all the zombie stuff.....i guess he really did it remarkably well
as for this according to an interview with him that i read he basically wanted to write a stern biography of Lincoln's life from birth to death and keep it historically accurate but added vampires and vampire hunting to the story.....he did a great job on both ends.....its like an educations romp....with vampires
....seriously a very fun book to read
