Dawn's Early Light. Ministry of Peculiar Occurrences, #3

Working for the Ministry of Peculiar Occurrences, one sees innumerable technological wonders. But even veteran agents Braun and Books are unprepared for what the electrifying future holds in the third novel in the steampunk adventure series. After being ignominiously shipped out of England following their participation in the Janus affair, Braun and Books are ready to prove their worth as agents. But what starts as a simple mission in the States-intended to keep them out of trouble-suddenly turns into a scandalous and convoluted case that has connections reaching as far as Her Majesty the Queen.
Even with the help of two American agents from the Office of the Supernatural and the Metaphysical, Braun and Books have their work cut out for them as their chief suspect in a rash of nautical and aerial disasters is none other than Thomas Edison. Between the fantastic electric machines of Edison, the eccentricities of MoPO consultant Nikola Tesla, and the mysterious machinations of a new threat known only as the Maestro, they may find themselves in far worse danger than they ever have been in before.
