The novel is presented as two sets of letters two thousand years apart. The first set is the first-century epistles of a nonphysical extraterrestrial trapped in human form whose investigations of Earth accidentally trigger the rise of Christianity. The second set are the digital-age emails of microbiologist Lillian Oberland to her cousin Michael, a public school biology teacher championing evolution in his classroom and battling the wrath of Creationist parents.
