I mostly kid. It's fine.
Deeply smart and enjoyable. Takes the premise and runs hard with it. Structurally it's very good; starting with something resembling a suite of short stories before pivoting into something larger. The midpoint lull is manageable and sticks the landing with a lovely existential-dread-inducing finale.
An enjoyable and well informed trip through England's medieval rulers though the cosy lens of the national treasure that is David Mitchell. That it took me over 2 years to finish is no indication of quality. Each chapter was mostly dedicated to a single individual, and each could stand up well on their own.
This did mean, for me at least, that it provided opportunities for prolonged leisurely breaks from the book where I'd distract myself with more cliffangery reading materials for months at a time.. but I'd always be able to come back, returning into the welcoming world of a numbered Richard, Henry or Æthelstan, and their somewhat storied lives. Glad I took the time, would completely recommend.
