Omon Ra is a fun little book about the Soviet space program. Much of the humor relies on a heavy context of Soviet society, but there's also some crude slapstick, one of the best kinds. My favorite parts were when Dr. Henry Kissinger stabbed the man in a bear suit and when the tampon fell out of the cosmonaut's nose. 
 The book is not just silly humor and puns though. There's something stranger and more mystical here, and the slow-burning pain of the narrator's own life. The moon is not a place of adventure stories here, but a cold and silent place millions of miles from the rest of humanity. Much of this book is lonesome and deeply sad.
