A girl with a clockwork heart must make every second count.
When Penny Farthing nearly dies, brilliant surgeon Calvin Warwick manages to implant a brass Ticker in her chest, transforming her into the first of the Augmented. But soon it s discovered that Warwick killed dozens of people as he strove to perfect another improved Ticker for Penny, and he s put on trial for mass murder.
On the last day of Warwick s trial, the Farthings factory is bombed, Penny s parents disappear, and Penny and her brother, Nic, receive a ransom note demanding all of their Augmentation research if they want to see their parents again. Is someone trying to destroy the Farthings...or is the motive more sinister?
Desperate to reunite their family and rescue their research, Penny and her brother recruit fiery baker Violet Nesselrode, gentleman-about-town Sebastian Stirling, and Marcus Kingsley, a young army general who has his own reasons for wanting to lift the veil between this world and the next. Wagers are placed, friends are lost, romance stages an ambush, and time is running out for the girl with the clockwork heart.
