'Grisly, addictive fun . . . I devoured it in 24 hours' – Emilia Hart, author of Weyward

In deepest winter, beware the coldest hearts . . .

London, 1850. Constance Horton has disappeared.

Maude, her older sister, knows only that Constance abandoned the apothecary they call home, and, disguised as a boy, boarded a ship bound for the Arctic. She never returned. ‘A tragic accident’, the Admiralty called it. But Maude Horton knows something isn’t right.

When she finds Constance’s journal, it becomes clear that the truth is being buried by sinister forces. To find answers – and deliver justice for her sister – Maude must step into London’s dark underbelly, and into the path of dangerous, powerful men. The kind of men who seek their fortune in the city’s horrors, from the hangings at Newgate to the ghoulish waxworks of Madame Tussaud’s.

It is a perilous task. But Maude has dangerous skills of her own . . .
