Two post-docs at the end of their school days journey into Hell to try and bring back the soul of their mentor, Professor Jacob Grimes. Along the way, they discuss paradoxes, depictions of Hell, the many sufferings of grad school, their personal failings, and the many different ways great people can have failed legacies. It works best when it is smart and funny (and alas Kuang abandons this combination for a fair chunk of the novel’s center) and seems a quite important book, just one as flawed as the book’s characters.
