Marta Morros Serret Book order (chronological)

In a small back alley in Tokyo, there is a café which has been serving carefully brewed coffee for more than one hundred years. But this coffee shop offers its customers a unique experience: the chance to travel back in time. But the journey into the past does not come without risks: customers must sit in a particular seat, they cannot leave the café, and finally, they must return to the present before the coffee gets cold . . .

Bookish high school student Rintaro Natsuki is about to close the secondhand bookshop he inherited from his beloved grandfather. Then, a talking cat named Tiger appears with an unusual request. The cat needs Rintaro's help to save books that have been imprisoned, destroyed and unloved. Their mission sends this odd couple on an amazing journey, where they enter different labyrinths to set books free. Through their travels, Tiger and Rintaro meet a man who locks up his books, an unwitting book torturer who cuts the pages of books into snippets to help people speed read, and a publisher who only wants to sell books like disposable products. Then, finally, there is a mission that Rintaro must complete alone...
