Sea of Tranquility is the latest novel by award-winning writer Emily St. John Mandel. She’s a literary writer who also is a huge commercial success and, incidentally, perennially appears on Barrack Obama’s yearly list of favorite books. This novel involves time travel. I’m not normally a science fiction fan, but she’s fundamentally a skilled literary novelist who likes to explore big ideas. I thoroughly enjoyed this book. Kirkus Reviews calls it exciting to read, relevant, and satisfying:
