Paul Russell's delicately layered, richly textured novels have won him widespread acclaim as one of the finest contemporary American novelists. "Sea of Tranquillity," possibly his most ambitious and rewarding novel, traces a disintegrating nuclear family across two tumultuous decades of American life - from the early '60s to the '80s - and is told in a quartet of voices: astronaut Allen Cloud, his wife, their gay son, Jonathan, and his friend/lover. Ranging in time and emotion from the optimism of the first moon shot to the dark landscape of the age of AIDS, "Sea of Tranquillity" is an extraordinary and compelling novel.
