Cogheart Adventures

Thirteen-year-old Lily Harman always dreamed of adventure. A strong-willed girl, Lily felt trapped in a life of Victorian stuffiness at her prim boarding school. But after her father-a famous inventor-disappears on a routine zeppelin flight, Lily's life gets turned upside down. Now cared for by her guardian, the heartless Madame Verdigris, Lily is quite certain that she's being watched. Mysterious, silver-eyed men are lurking in the shadows, just waiting for their chance to strike. But what could they possibly want from her? There are rumors, Lily learns, that her father had invented the most valuable invention ever made-a perpetual motion machine. But if he made such a miraculous discovery, he certainly never told Lily. And all he left behind is a small box-with no key, no hinges. With the help of a clockmaker's son, Robert, and her mechanimal fox, Malkin, Lily escapes London in search of the one person who might know something about her father's disappearance-and what he left behind.

It's hard to escape the secrets from the past. Storm clouds gather over Lily and Robert's summer when criminal mastermind the Jack of Diamonds appears. Jack is searching for the mysterious Moonlocket-but that's not the only thing he's after. Suddenly, dark secrets from Robert's past plunge him into danger. Jack is playing a cruel game that Robert is wrapped up in. Lily and Malkin, the mechanical fox, must stay one step ahead before Jack plays his final deadly card . . .

Old secrets can weigh heavy when you want to fly. Invited to a spectacular show by Slimwood's Stupendous Traveling Skycircus, Lily, Robert, and mechanical fox Malkin can't wait to jump aboard. But behind the daredevil acts of the bewitching bird-girl and other performers, something sinister lurks. And soon, the watchful ringmistress, Madame Lyon-Mane, reveals a deadly plan for Lily. Could the secrets of Lily's past hold their only chance at escape from this terrible trap?
