"Hearts are broken," Lillian Dyson carefully underlined in a book. "Sweet relationships are dead." But now Lillian herself is dead. Found among the bleeding hearts and lilacs of Clara Morrow's garden in Three Pines, shattering the celebrations of Clara's solo show at the famed Musée in Montréal.

Chief Inspector Gamache, the head of homicide at the Sûreté du Québec, is called to the tiny Québec village. There, he finds the art world gathered, and with it, a world of shading and nuance, a world of shadow and light. Where nothing is as it seems. Behind every smile, there lurks a sneer. Inside every sweet relationship, there hides a broken heart.

And even when facts are slowly exposed, it is no longer clear to Gamache and his team if what they've found is the truth, or simply a trick of the light.

Tom Cole, the grandson of a legendary local hero, has inherited an uncanny knack for reading the Niagara River's whims and performing daring feats of rescue at the mighty falls. A chance encounter between Tom and 17-year-old Bess Heath has an explosive effect. When they first meet on a trolley platform, Bess immediately recognizes the chemistry between them, and the feeling is mutual.

But the hopes of young love are constrained by the 1915 conventions of Niagara Falls, Ontario. Tom's working-class pedigree doesn't suit Bess's family, despite their recent fall from grace. Bess's father has been sacked from his position at a hydroelectric power company and has taken to drink, forcing her mother to take in sewing for the society women who were once her peers. Bess pitches in as she pines for Tom, but at her young age, she's unable to fully realize how drastically her world is about to change.

Set against the resounding backdrop of the falls, Cathy Marie Buchanan's carefully researched, capaciously imagined debut novel entwines the romantic trials of a young couple with the historical drama of the exploitation of the river's natural resources. The current of the river, like that of the human heart, is under threat: "Sometimes it seems like the river is being made into this measly thing," says Tom, bemoaning the shortsighted schemes of the power companies. "The river's been bound up with cables and concrete and steel, like a turkey at Christmastime."

Skillfully portraying individuals, families, a community, and an environment imperiled by progress and the devastations of the Great War, The Day the Falls Stood Still beautifully evokes the wild wonder of its setting, a wonder that always overcomes any attempt to tame it. But at the same time, Buchanan's tale never loses hold of the gripping emotions of Tom and Bess's intimate drama.

The optimism of the early sixties, infused with the excitement of the space race and the menace of the Cold War, is filtered through the rich imagination of high-spirited, eight-year-old Madeleine, who welcomes her family's posting to a quiet Air Force base near the Canadian border.

Secure in the love of her beautiful mother, she is unaware that her father, Jack, is caught up in a web of secrets. When a very local murder intersects with global forces, Jack must decide where his loyalties lie, and Madeleine will be forced to learn a lesson about the ambiguity of human morality—one she will only begin to understand when she carries her quest for the truth, and the killer, into adulthood twenty years later.
