On a bustling road in Sydney, Australia, lies a nondescript storefront known simply as the Time Travel Agency. Inside, you’ll be welcomed by the smell of fresh-brewed coffee, a selection of baked goods…and a question: Where in time do you wish to go? You can go whenever you wish into the past, and there’s no fear of altering the present. Is it a hoax? And if it’s real, what’s the catch? When single mother Anna is offered a job at the agency, she glimpses the possibility of happiness. Meanwhile, Teddy is a customer hoping to untangle his recently imploded marriage. And Jade, who has a deeply buried secret, despises the agency for offering false hope. Anna, Teddy and Jade leap headlong into time, hurtling on a crash course toward one another.

Twenty years ago, Abigail Sorenson’s brother, Robert, went missing one day before her 16th birthday, never to be seen again. That same year, she began receiving scattered chapters in the mail of a self-help manual, The Guidebook, whose anonymous author promised to make her life soar to heights beyond her wildest dreams. The Guidebook’s missives have remained a constant in Abi’s life --- through her family’s grief over her brother’s disappearance, a move across continents, the devastating dissolution of her marriage, and the new beginning as a single mother and café owner in Sydney. Now, two decades after receiving those first pages, Abi is invited to an all-expenses-paid weekend retreat to learn “the truth” about The Guidebook.
