Two book recommendations

Very high recommendations for the following books, which I stockpiled in advance of my trip to China, but ended up reading most of before departure...

The Lost Books of the Odyssey by Zachary Mason, a Borges-ian retelling of the Odyssey in 44 short stories.

Perfect Rigor by Masha Gessen, on Grisha Perelman and the proof of the Poincare / Geometrization Conjecture. I already knew a bit about the completion of Hamilton's program thanks to colleagues who work on Ricci flow. What I found most interesting in the book is the insider description of the Soviet math system, including the nurturing of young talents and the training for competitions like the IMO.
