About this book:

During the Franco-Prussian War, as the Prussian army encircles Paris and cuts off its food supply, botanist Elise Moreau refuses to surrender to despair. Instead, she transforms the city into a living herbarium, launching "The Foragers' School" to teach starving citizens how to identify and prepare edible weeds, roots, and urban flora. Alongside the pragmatic Sergeant Duval and the cynical chemist Dr. Dubois, Elise turns neglected parks and cracks in the pavement into a vital larder, developing innovative recipes for acorn bread, lichen jelly, and coffee substitutes to sustain the city's body and spirit.

As the winter deepens and the bombardment intensifies, the story follows the scientific and ethical struggles of a populace living on the edge of survival. From the "Quiet Revolt of Roots" to the "Carbon Recovery" following a devastating fire in the university conservatory, the narrative explores the ingenuity of "siege botany." Elise's work transcends mere survival, fostering a "taxonomy of courage" and a social contract rooted in the sustainable management of the city’s few remaining resources.

The novel concludes with the reopening of the city gates during an armistice, revealing a scarred but resilient population. Having survived on the very weeds they once stepped over, the citizens emerge with pockets full of seeds and a newfound respect for the natural world. *The Siege Botanist* is a testament to the power of scientific knowledge and communal solidarity, illustrating how a discipline as quiet as botany can become a powerful tool of resistance and a blueprint for rebuilding a broken world.
