This week, pair up a nonfiction book with a fiction title. Maybe it’s a historical novel and the real history in a nonfiction version, or a memoir and a novel, or a fiction book you’ve read and you would like recommendations for background reading.


My pair of books are both about Jewish watchmakers in World War II.

The Watchmakers

by Henry Lenga, Scott Lenga
Setting: Poland
Genres: Biography & Autobiography / Personal Memoirs
Published on June 28, 2022
Pages: 352

Told through meticulous interviews with his son, this is an extraordinary memoir of endurance, faith, and a unique skill that kept three brothers together—and alive—during the darkest times of World War II.

Harry Lenga was born to a family of Chassidic Jews in Kozhnitz, Poland. The proud sons of a watchmaker, Harry and his two brothers, Mailekh and Moishe, studied their father’s trade at a young age. Upon the German invasion of Poland, when the Lenga family was upended, Harry and his brothers never anticipated that the tools acquired from their father would be the key to their survival.

Under the most devastating conditions imaginable—with death always imminent—fixing watches for the Germans in the ghettos and brutal slave labor camps of occupied Poland and Austria bought their lives over and over again. From Wolanow and Starachowice to Auschwitz and Ebensee, Harry, Mailekh, and Moishe endured, bartered, worked, prayed, and lived to see liberation.

Derived from more than a decade of interviews with Harry Lenga, conducted by his own son Scott and others, The Watchmakers is Harry’s heartening and unflinchingly honest first-person account of his childhood, the lessons learned from his own father, his harrowing tribulations, and his inspiring life before, during, and after the war. It is a singular and vital story, told from one generation to the next—and a profoundly moving tribute to brotherhood, fatherhood, family, and faith.


I bought this book for the husband after seeing it during last year’s Nonfiction November. The husband is a watch collector so I knew this would interest him. He did find it fascinating. When he was finished he passed it on to a Jewish friend who likes to read about Jewish history.

About a month after he read that book, I picked up this fiction book and immediately knew this had to be my pairing for this year.

The Book of Lost Hours

by Hayley Gelfuso
Genres: Fiction / Science Fiction / Time Travel
Published on August 26, 2025
Pages: 400
Format: eBook Source: Library

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.


Lisavet’s father is a Jewish watchmaker in Germany. He makes watches that let people travel into the time space – a between-world filled with memories. When soldiers come for him during Kristallnacht, he shoves Lisavet into the time space to keep her safe. With no way to get out, she grows up there and learns its secrets until competing spies from the Soviet Union and the United States discover her presence.

The book was fairly high concept and I’m not entirely sure that it worked. But I liked the idea of Jewish watchmakers making time-bending watches in 1930s Germany.
