Rachel Hoffman is one of the most inexplicable people in the cosmos and may offer the first proof that we are living in a multiverse. The idea of a “multiverse” proposes that an infinite number of universes exist in parallel with our own. These universes differ in a variety of physical properties, featuring multiple Big Bangs, space bubbles and maybe even an alternate version of you, where, even though you are a giant mushroom, you still want to read Rachel’s debut novel, Packer and Jack.
