It's twenty years after the War of the Immortal Souls, and thanks to the sacrifices of the previous generation, today's young people have always enjoyed peace. However, things can change quickly, and it's time once again for the world to prepare itself to fight.

Hill knew two definitive things about Skyline. The first: they hated the Immortal Men and their goal was to imprison them all. The second: they would use any method to accomplish this task, including torture and deception. Book One.

Methods get drastic and sneaky and Elena has no choice but to remain involved. Suddenly, it seems as though victims are at fault, enemies were never enemies, and allies were never allies at all. Part 8.

A royal wedding proves to be a catalyst for everything good and everything bad at the same time. New plans are set in motion on both sides, and Elena suddenly finds herself in a position where everyone begins to rely on her just a little too much. Part 7.

Help begins to trickle down from the King himself, and soldiers and resources finally bring some relief to Elena and the Seven Sons. The cavalry has arrived, but it still might not be enough to defeat Hunt and spoil his plans. Part 6.

Having officially left reality behind for good, Elena chases demons and recovers allies, all the while dangling above the clouds on board the floating Kingdoms of the Seven Sons. Part 4.

With a face to their enemy, not-so-smart Elena and the extremely dysfunctional Seven Sons must abandon their fantasies and flying Kingdoms if they hope to survive another encounter. Part 3.

Elena's use for mundane reality is just about over. She continues her adventures on board the floating Kingdoms, battling monsters, interacting with Seven Sons, and using her poor judgment to establish who's the good guy and who's the bad guys. Part 2.

Elena has little use for mundane reality, but her detachment from the real world to indulge in delusions aboard the floating castle called the Kingdom of Rain with an unstable captain proves to be both dangerous and, at times, hilarious. Part 1.
