The real world has caught up with Arden Thatcher, and there are pictures to prove it. As she sails back to Nordania on the arm of Declan Levington, the prime minister's son and heir presumptive to Nordania, danger lurks around every corner. And not just in the form of her betrayer, Beck Hermeston, who spends his days in the brig below deck. Powerful people suspect what she's been up to, and have both means and motives to ensure she doesn't succeed. But between state dinners and press conferences, Arden searches for the mysterious Embers, a group of institute graduates who hold the potential to turn Nordania on its head. Yet with every step closer to home-and to a very public wedding-Arden discovers that those who would stop her are much closer and more powerful than she ever expected, putting everyone involved in her plan to end the benefactor system in question. Now, Arden must decide how far she's willing to go to ignite the spark of change, and who she's willing to be when it's over. Filled with elaborate world-building, political intrigue, and a fierce belief in independence, When Sparks Ignite is the gripping finale to Arden's tale.
