"Atmospheric...a compelling supernatural mystery that will hold a reader's attention right up to the last page."- Library Journal

Francine Thwaite has lived all her fifty-five years in her family's ancestral home, a rambling Elizabethan manor in England's Lake District. No other living soul resides there, but Francine isn't alone. There are ghosts in Thwaite Manor, harmless and familiar. Most beloved is Bree, the mischievous ghost girl who has been Francine's companion since childhood.

When Francine's estranged sister, Madeleine, returns to the manor after years away, she brings with her a story that threatens everything Francine has always believed. It is a tale of cruelty and desperation, of terror and unbearable heartache. And as Francine learns more about the darkness in her family's past-and the role she may have played in it-she realizes that confronting the truth may mean losing what she holds most dear.

As moving and poignant as it is chilling, Her Little Flowers is a story of grief and enduring love-and of the haunting regrets only forgiveness can dispel.
