"A fascinating meditation on the many ways traveling through time can change a person."—HelloGiggles "This genre-bending, time-bending debut will appeal to fans of Doctor Who, dystopian fiction, and life's great joy: friend groups."—Refinery29 An “astonishing” time-travel debut about science and friendship, perfect for fans of The Power and Hidden Figures (The New York Times) In 1967, four female scientists worked together to build the world’s first time machine. But just as they are about to debut their creation, one of them suffers a breakdown, putting the whole project—and future of time travel—in jeopardy. To protect their invention, one member is exiled from the team—erasing her contributions from history. 50 years later, time travel is a big business. 20-something Ruby Rebello knows her beloved grandmother, Granny Bee, was one of the pioneers, though no one will tell her more. But when Bee receives a mysterious newspaper clipping from the future reporting the murder of an unidentified woman, Ruby becomes obsessed: could it be Bee? Who would want her dead? And most importantly of all: can her murder be stopped? Traversing the decades and told from alternating perspectives, The Psychology of Time Travel introduces a fabulous new voice in fiction and a new must-read for fans of speculative fiction and women’s fiction alike.
