PRE-ORDER NOW: the stunning new novel from the Sunday Times bestselling author of The Betrayals and The Good Girl.

After a chaotic childhood, Grace Vermuyden is determined her own daughters will fulfil the dreams denied to her. Lilly is everyone's golden girl, the popular, clever daughter she never had to worry about. So when she mysteriously collapses in class, Grace's carefully ordered world begins to unravel.

Dark rumours swirl around their tight-knit community on the edge of the Fens as everyone comes up with their own theories about what happened. Consumed with paranoia, and faced with increasing evidence that Lilly has been leading a secret life, Grace starts to search for clues.

Left to her own devices, ten-year-old Mia develops some wild theories of her own that have unforeseen and devastating consequences for the people she loves most.

Beneath the Surface explores the weight of the past upon the present, the burden of keeping secrets and what happens when children get caught in the undercurrents of adult relationships.
