In the final book in Gosling's Diamond Thief Trilogy, "Little Bird" Rémy Brunel, the lithe, graceful, and deft thief of Gustave's circus, has turned away from her life of crime to join forces with Thaddeus Rec and the elder Desani to travel to India. Along with J and Dita, they fly J's jerry-rigged hot-air-balloon airship from France to the hidden mountains and valleys of India to save the world from destruction by the Sapphire Cutlass and her loyal, if bizarre, superstrong sapphire-encrusted soldiers. Gosling's contorted story line spins a fanciful and exciting adventure that has Rémy reuniting with her long-lost twin brother, Kai, after being captured by his pirate crew. More magical than historical, more swashbuckling adventure than sweet romance, this remains a steampunk, happily-ever-after for "Little Bird" Rémy and "her policeman" Thaddeus Rec.
