The Singing Heart

By John Carver

On the night before Christmas, the mechanical heart of the city stopped beating.
The gentle humming of the Duchaine house cuts out. In its place, a green and toxic vapour seeps under the doors. Rusted, grinding shadows have just ransacked the parlour - taking the presents, and something far worse: their father's last, secret invention.
For Olympia, a young engineer with a razor-sharp mind, and her brother Hippolyte, an impulsive boy with grease under his fingernails, the hunt begins. From the biting wind on frozen zinc rooftops to the choking heat of the industrial catacombs, they have only one lead: a trail of glowing oil in the snow.
Who turned the city's harmless toys into brass nightmares? And what is the monstrous shadow that makes the very foundations of the Eiffel Tower tremble with a howl of steam?
They have until Christmas morning to find what was stolen. After that, it will be too late.
A steampunk Christmas adventure for readers aged 9 and up - and for anyone who likes machines that make far too much noise. Perfect for fans of Philip Reeve and Chris Riddell.
