An alien is sent to earth to inhabit the body of a mathematician in order to prevent his recent discovery from allowing human advancement into deep space travel. But the longer the alien spends on earth, the more sympathy and fondness he develops for his "family" and all of humankind (thanks in no small part to Emily Dickenson and the Beach Boys). This makes them infinitely more difficult to kill. Lovely start to the year. 4⭐️
