Laevium by Ruxandra Tarca

London, 1895. Ten years after the Reform, Victorian England is geared towards technology full-steam ahead, under the watchful eye of the Engineers Order and the Royal Family. Only that not everything is as great as it seems. Dark experiments and plots are threatening to shatter the establishment, and airship engineer Jasper Kendall Asher has only until the next Engineers World Gathering to uncover them – and reveal the truth behind his twin brother’s death.
