My sister got me this two days ago.
Urgh. If this were fanfiction I'd wouldn't have lasted past the first chapter. I'm about 100+ pages into it and I can't seem to have the strength to read the rest.
POV changes EVERY PARAGRAPH, with no breaks. Sometimes POV changes every other sentence. It doesn't help that everything is a flashback within a flashback within a flashback. Heaven help you if there are multiple people on the scene other than Abe Lincoln. And there's a random narrator voice that pops up as well. Its a wild mass guess who is speaking and which POV is being taken.
As for the plot, its just Abe Lincoln's life, except that every tragedy in his life was caused by vampires (for example, his grandfather was killed by vampires rather than native americans, his mother and first girlfriend died of vampires rather than typhoid, etc). Then he goes out to kill them, more often than not a few sentences on how he chops off their head. If you're expecting some baddass actions scenes, you'll be disappointed. Vampires are supposedly much stronger and much faster, capable of ripping people in half and agile enough to jump across tree tops, but after reading a plain "I threw my axe, it hit, he died" several times it gets kinda boring, rapidly.
I was hoping to get "Pride, Prejudice and Zombies" by the same author, but if this is his writing style, forget it.
