A sweeping debut novel following an American artist who returns to Germany—where she fell in love and had a child decades earlier—to confront her past at her former mother-in-law’s funeral. 

It’s 1971 when Louise leaves Oregon for Düsseldorf, a city grappling with its nation’s horrific recent history, to study art. Soon she’s embroiled in a scene dramatically different from the one at home, thanks in large part to Dieter, a mercurial musician. Their romance ignites quickly, but life gets in the way: an unplanned pregnancy, hasty marriage, the tense balance of their creative ambitions, and—finally, fatally—a family secret that shatters Dieter, and drives Louise home. 

But in 2008 she’s headed to Dieter’s mother’s funeral. She never returned to Germany, and has since remarried, had another daughter, and built a life in Oregon. As she flies into the heart of her past, she reckons with the choices she made, and the ones she didn’t, just as her family—current and former—must consider how Louise’s life has shaped their own, for better and for worse. 

Exquisitely balanced, expansive yet wonderfully intimate, Lifelines explores the indelible ties of family; the shape art, history, and nationality give  to our lives; and the ways in which we are forever evolving, with each step we take, with each turn of the Earth.

"What a graceful, attentive, and beautiful debut. Among Diehl’s abundant gifts are a wonderful eye for the telling detail, a lovely narrative patience, a playful comfort with structural panache, a genuine affection for her characters, and a keen understanding of the ways in which families actually work. The novel thrums with the sadness of life, and also with its comforts." 

—George Saunders 

"A fascinating interrogation of complicated histories—both cultural and personal—as well as an exploration of the roles that art, family, and creativity play in our lives.” 


"Gorgeous...Lifelines has everything you'd want in a book: family secrets, love triangles, and beautiful writing." 


"Richly textured, kaleidoscopic." 

O Magazine 



Saratoga Living 

“The family drama is interlaced with beautiful, meticulously detailed scenes…“Lifelines” weaves a rich tapestry out of interconnected personal histories and shows that we are all greater than the sum of our parts.”


“From the collision of art and family to the prolonged misunderstandings between characters living across cultures, Heidi Diehl has crafted a complex novel that builds with subversive power, to an assured ending. With riveting precision, Lifelines addresses an inevitable reality of adulthood: for better or worse, we remain beholden to all our relationships, even those we choose to end.” 

—Idra Novey, author of Ways to Disappear and Those Who Knew 

Lifelines is a true tapestry of a book, intricate and elegantly told, about family and nationhood, and the ways that each generation is shaped by the one that came before it. Diehl writes with a remarkable emotional intelligence that will stay with me for a very long time.” 

—Julia Pierpont, New York Times-bestselling author of Among the Ten Thousand Things and The Little Book of Feminist Saints 


"Lifelines is an arresting portrait of selves left behind and selves discovered. Heidi Diehl writes with precision and heart about home, history, identity and the lives we might have led." 

—Ramona Ausubel, author of Sons and Daughters of Ease and Plenty and Awayland 


"At once moving and intelligent, Heidi Diehl’s Lifelines is about history and politics, memory and art. It spans continents and generations, and it earns its ambition. It’s a riveting, important debut." 

—Joshua Henkin, author of Matrimony and The World Without You

"Diehl's debut confidently handles these cultural and historical complexities and is equally fluent in depicting the concerns and processes of visual artists and musicians. A serious, nuanced portrait of a family of creative people as their decisions, large and small, play out in their lives."


"Diehl finds the bittersweet heartache of retrospection, and compassionately explores how art helps heal. This complex, intimate story memorably portrays what it looks like to reckon with one’s choices and to feel both uncertainty and peace."

Publishers Weekly

"A strong debut novel from a writer with a talent for character building."
