DNF. 1.5 stars.
I was just very...confused with this book. Didn't help that each little snippet quoted from various works of literature to tell of the grand dinner the Lincolns' threw while their son was sick upstairs was quoted and cited at the end of each snippet. And this was every other sentence or so. If I was reading, I could gloss over the citations, but with an audiobook it was very infuriating.
Otherwise I was just not on board with this strangeness.
