What is the setting in the novel, The Iron Daughter?

The Iron Daughter takes place primarily in the world of Faery, a world unknown to most humans who live in the mortal realm. Faery includes two well-established kingdoms, Summer and Winter, who pass the Scepter of the Seasons back and forth twice every year, at the equinox, to maintain the balance of the seasons. The two kingdoms coexist, usually peacefully, sometimes grudgingly. A third kingdom, the Iron Kingdom, has evil intentions toward the Summer and Winter Courts. A fourth kingdom, the Between, was established by a powerful fey who had been banished from Faery. The Between lies between Faery and the mortal world. Part of the story takes place in the mortal realm as well, where main character Meghan grew up. The stolen Scepter of the Seasons is hidden in Silicon Valley, and Meghan is forced to rescue her family who live in Louisiana.
