Charlotte has always known she is different. Where other young women see their destiny in marriage and motherhood, the reclusive Charlotte wants only to work with her father in his stationery business; perhaps even run it herself one day. Then Flora Dalton bursts through the shop door and into Charlotte's life -- and a new world of baffling desires and possibilities seems to open up to her. But Melbourne society of the 1890s is not built to embrace unorthodoxy. When tragedy strikes and Charlotte is unmoored by grief, she finds herself admitted to Kew Lunatic Asylum 'for her own safety'. There she learns that women enter the big white house on the hill for many reasons, not all of them to do with lunacy. That her capacity for love, loyalty and friendship is greater than she had ever understood. And that it will take all of these things -- along with an unexpected talent for guile -- to extract herself from the care of men and make her way back to her heart's desires.
