Thank you to NetGalley, the author, and the publisher for this ARC in exchange for my honest review.
Throughout the book, there is a visible trend: the author's original thoughts and conclusions are supported by sometimes poorly cited ideas, while citations are used to support those secondary ideas and are only tangentially related to the thoughts and conclusions that are given as the meat of each chapter. The bulk of the claims made in this work are therefore unverifiable and impossible to take as serious history. It is admirable that the author seeks to illuminate a different perspective on an established and explore ideas that do have some merit within the historical community, but to present these ideas as unquestioned fact without sufficient primary evidence does the book a grave disservice. While the book is extremely entertaining, it's difficult and sometimes even impossible to fact check or proof relevance of the author's many citations. For instance, Citation 488, to paraphrase, states that a real person was made into a character for a Netflix drama. What, exactly, does that have to do with either Lincoln or Francis Tumblety, other than fluffing up the number of citations? Stating that someone was a character on a TV show is not a source, nor is it compelling information. Abraham Lincoln was a character in Abraham Lincoln, Vampire Slayer, but that is just as irrelevant as one of the many sources within this book. Furthermore, there are exactly 576 citations within the book, and no sources cited page whatsoever.
Additionally, the author seems to have some sort of personal vendetta against what he terms “hetero-historians,” a term which occurs no less than six times across the book, who seem to be out to deny that LGBT people exist and that Lincoln, or any other historical figure mentioned within the book, could possibly be LGBT. The entire chapter about Lincoln's supposed sexuality seems to serve as an “aha! Gotcha!” written to spite these “Hetero-historians”. Lincoln's sexuality is hotly debated academically by people on every side of the fence. Quite simply it's...problematic to have this debate in the first place about a man who lived 159 years ago and would have not even had the word “homosexual” to define himself by. The word "homosexual" was coined in 1868, while Lincoln died in 1865. “Straight washing” happens all the time in the historical fields, and LGBT history gets brushed under the rug to suit bigoted, hateful agendas. However, presenting the author's suspicions as a undeniable fact is where I, an LGBT person myself, take my issue.
In conclusion, the premise of the book is interesting, and no doubt will catch people's attention, but I am somewhat dubious of the veracity of its contents, and would recommend other books on Lincoln or Jack the Ripper over this one.
