“Jacob couldn't really hear the sound of the other landships over the humming and cranking of his own. He heard the whistle of steam coming from the pipes and the latching of the iron tracks as they clicked into place. He heard gears adjusting, the rhythm of the pumps, the revving of the engine, and the fuming of the furnace. He also heard Andil’s heavy breathing, and he heard his own heart’s heavy beating.” HeartWarVehicleSteamTracksEngineTankLandship Book:Hopebreaker Source: Hopebreaker
