Steamheart

"Mekaela never questioned her place in the world. As a Ward of the States, beholden to the Lady-Captain of the flagship Golden Matriarch, Mekaela worked every day in the steam lines, fulfilling her obligations to her benefactor and trying to stay out of trouble. Then the pirates came, and all of her secrets came spilling out. Now she has to make a choice: Join the pirates, embrace her power and defy the Nobility, or go for a short walk, with a very long drop!" – quoted from this book's product page on Amazon.com as of 2017-07-06.
