The Ingenious Mechanical Devices Books 1-3: The Earl of Brass, The Gentleman Devil, and The Earl and the Artificer. The Collected Ingenious Mechanical Devices Series, #1

The Earl of Brass: Eilian Sorrell is no stranger to cheating death, but when a dirigible accident costs him his arm, he fears his days of adventuring are over. Across London, Hadley's brother is dead and she is forced to pick up the pieces of the family business. When clients begin turning her away, she fears she will fail until she crosses paths with the enigmatic Lord Sorrell. In exchange for a new arm, he offers her a chance at adventure in the deserts of Palestine.
Will they make it out alive or will they, too, be buried beneath the desert sands?The Gentleman Devil: When Immanuel Winter set off to the banks of the Thames, he never thought his life would be changed forever. Emmeline Jardine, a young Spiritualist medium, drowns, but the potion given to Immanuel by his mother brings her back from the dead and irrevocably intertwines their souls. Understanding the potential of such an elixir, the ruthlessly ambitious Alastair Rose knows securing the mysteries of death will get him everything he desires: power, a title, but more importantly, dominion over the dead and the living.
All that stands between Lord Rose and his prize is the boy who refuses to die and the girl who shares his soul. The Earl and the Artificer: As Eilian struggles to reconcile his new roles as husband and earl, he finds his ancestral home and the surrounding town of Folkesbury are not as they first appear. Behind a mask of good manners and gentle breeding lurks a darker side of Folkesbury. Soon, Eilian and Hadley become entangled in a web of murder, theft, and intrigue that they may never escape, with the manor at the heart of it all.
Something long thought lost and buried within Brasshurst's history has been found-something worth killing for.
