For fans of The Min­istry of Time and The Mid­night Library, a sweep­ing, unfor­get­table nov­el fol­low­ing two remark­able women mov­ing between post­war and Cold War-era Amer­i­ca and the mys­te­ri­ous time space, a library filled with books con­tain­ing the mem­o­ries of those who bore wit­ness to his­to­ry.

Enter the time space, a soar­ing library filled with books con­tain­ing the mem­o­ries of those have passed and accessed only by spe­cial­ly made watch­es once passed from father to son — but most­ly now in gov­ern­ment hands. This is where eleven-year-old Lisavet Levy finds her­self trapped in 1938, wait­ing for her watch­mak­er father to return for her. When he doesn’t, she grows up among the books and specters, able to see the world only by sift­ing through the mem­o­ries of those who came before her. As she real­izes that gov­ern­ment agents are enter­ing the time space to destroy books and main­tain their pre­ferred ver­sion of his­to­ry, she sets about sav­ing these scraps in her own vol­ume of mem­o­ries. Until the appear­ance of an Amer­i­can spy named Ernest Duquesne in 1949 offers her a glimpse of the world she left behind, set­ting her on a course to change his­to­ry and pos­si­bly the time space itself.

In 1965, six­teen-year-old Amelia Duquesne is mourn­ing the dis­ap­pear­ance of her uncle Ernest when an enig­mat­ic CIA agent approach­es her to enlist her help in track­ing down a book of mem­o­ries her uncle had once sought. But when Amelia vis­its the time space for the first time, she real­izes that the past — and the truth — might not be as lin­ear as she’d like to believe.

Per­fect for fans of The Mid­night Library and The Min­istry of Time, The Book of Lost Hours explores time, mem­o­ry, and what we sac­ri­fice to pro­tect those we love.
