In 1968, after his father is assassinated by the KGB, Alexander Karpenko flips a coin to decide whether he should immigrate (desperately) to London or to New York. Readers get two versions of what might have happened, depending on the outcome of that flip.  Booklist says that Archer’s “writing and characterizations are superb. Also, “the book features several plot twists…that should make readers’ jaws drop”.
