Everyone in Shaker Heights was talking about it that summer: how Isabelle, the last of the Richardson children, had finally gone around the bend and burned the house down.

In Shaker Heights, a placid, progressive suburb of Cleveland, everything is meticulously planned – from the layout of the winding roads, to the colours of the houses, to the successful lives its residents will go on to lead. And no one embodies this spirit more than Elena Richardson, whose guiding principle is playing by the rules.

Enter Mia Warren – an enigmatic artist and single mother – who arrives in this idyllic bubble with her teenage daughter Pearl, and rents a house from the Richardsons. Soon Mia and Pearl become more than just tenants: all four Richardson children are drawn to the alluring mother-daughter pair. But Mia carries with her a mysterious past, and a disregard for the rules that threatens to upend this carefully ordered community.

When the Richardsons' friends attempt to adopt a Chinese-American baby, a custody battle erupts that dramatically divides the town and puts Mia and Mrs. Richardson on opposing sides. Suspicious of Mia and her motives, Mrs. Richardson becomes determined to uncover the secrets in Mia's past. But her obsession will come at unexpected and devastating costs to her own family – and Mia's.

Little Fires Everywhereexplores the weight of long-held secrets and the ferocious pull of motherhood-and the danger of believing that planning and following the rules can avert disaster, or heartbreak.
