In Atenas, the dark summoners of the Khalan press their attack. Alena's discovery of how to use spirit gives them an advantage, but the Khalan have numbers, and have infiltrated much of the city. Forced to lead, Alena struggles with the expectations now placed upon her. Returned from captivity and now a master of summoning, Ciara is the key to stopping the Khalan and Tenebeth for good, but she will need the help of both the warriors of Atenas and the remnants of Hyaln.

Ciara has traveled to the barracks, but the promised teaching has not come to pass, leaving her worse off than before and her people without the nya'shin for protection. If she can't master the summoning, she fears the darkness will claim her. But now that the darkness has revealed itself, Jasn must find a way to save Alena from her connection to the draasin before that connection kills her. Only then can he search for whether Katya was destroyed by the darkness or learn if he can still save her.

Jasn, a warrior known as the Wrecker of Rens, seeks vengeance for the loss of his beloved to the deadly draasin during the Endless War, wanting nothing more than to sacrifice himself in the process. When an old friend offers a dangerous chance for him to finally succeed, the key to understanding what he finds requires him to abandon all that he believes. Ciara, a water seeker of Rens living on the edge of the arid waste, longs for the strength to help her people.

Having stopped Lorren and saving the egg, Jason now faces his most dangerous threat as Lorach moves on Dragon Haven. With the city under attack from a strange new power, only with an understanding of the misfit dragons will Jason - and the dragons - finally be free. When even Dragon Haven seeks to use their power, Jason is forced to make a choice between the people who took him in and the dragons he pledged to protect.

Jason has secured a tentative peace for Dragon Haven. With his control over illusion, and the Lorach threat thwarted for now, his time is spent preparing for the next attack, knowing the Dragon Souls will not be easily stopped. An old ally to Dragon Haven returns, but Jason questions his motives - along with his techniques. Now, Jason must choose whether to stop the Dragon Souls or save them. Stopping Lorach for good might mean destroying the captured dragons. It's a choice Jason fears to make, but doing otherwise means betraying those who have come to rely upon him.

Now that his sister knows of the dragons, Jason doesn't feel as isolated in their small village. The connection to the dragons lets him protect his people along with the existence of the dragons. An attack on his home village forces Jason to go to Lachen and stop Therin for good. To do so, he'll need the help of all the dragon misfits, but can the forest dragon help him master the art of illusion in time for him to save his people?

Jason has returned to the normalcy of the mountain village, but nothing is as it had been. Now connected to the Ice Dragon and responsible for keeping his presence a secret, it won't be long before the Dragon Souls return. They know the Ice Dragon exists and will stop at nothing to control him. When the Ice Dragon makes a request of Jason to search for other dragons like him, how can he refuse? The search leads Jason away from home and into direct conflict with those searching for another dragon misfit. 

Jason spends his time trying to protect Dragon Haven and understand the dragon misfits now that he has prevented Lorach from using them. He searches for more misfits, but quickly learns he won't be able to save them all. When word of an attack on the Dragon Guard suggests Lorach is renewing their attempt to destroy the rebellion, Jason leaves to investigate. What he finds changes everything he knows about the misfits. Saving the dragons means risking everything he's gained. If he fails, the rebellion will fail and Dragon Haven will fall.

While trying to track down her brother, Sam discovers she isn't through with Marin quite yet. An attack proves that a traitor sympathetic to Marin remains active in the city, but training prevents Sam from finding answers. With the Thelns once more in the city, Elaine doesn't believe Sam should be involved in the search, which means she has to go off on her own. Doing so risks her position at the palace, but any other choice puts her brother in danger.    

No longer forced to hide his ability, Rsiran now Slides openly throughout the city as he helps it recover from the recent attack. Requirements of his time continue to mount, not only as he tries to help his friends, but new responsibilities to the guild force him to interact with the Elvraeth, where he discovers the uneasy alliance that exists between the guilds and the council. When one of the great crystals goes missing, that alliance is tested, and the quest to find the crystal leads him to realize a secret long hidden.

In the city of Verdholm, canals separate the highborns in the center sections of the city from the lowborns along the outer sections. The city is isolated, surrounded by a deadly swamp and steam fields which should protect the people of the city from the dangerous outside world. Until it doesn't. For Sam, an orphaned thief who wants only to protect her brother, protection means stealing enough so she can one day buy her way into a better section. She's a skilled thief, and when she's offered a job that can change everything for her, what choice does she have but to take it?

Forced into the heart of the Aisl Forest, Rsiran and the guilds regroup and try to find a way to reclaim the city from Venass and the Elvraeth council. Rsiran has stopped the production of shadowsteel, but Venass still possesses dangerous weapons, and what's more, one of the great crystals remains missing. Forced into an alliance with the mysterious Carth in order to find the crystal, they make new allies and discover the means to reclaim the city, but will it be too late?

Sam and Alec work to understand their connected magic, but the limited supply of easar paper limits them. Worse, Marin has again disappeared, leaving questions unanswered. How can they be ready for another Theln attack if they don't have an opportunity to train with their abilities? New power complicates everything. Sam wants to use it to continue taking jobs that will eventually buy her way into the nicer sections of the city, but Alec sees a higher purpose to their magic. 

No longer alone, Sam and Alec struggle to find time to continue their studies together. Sam knows that she is more than the lowborn she'd long believed, now living and training in the palace, but still doesn't feel as if she quite fits in. Worse, it seems as if Alec has moved on without her, preferring his new life in the university. Alec has quickly risen in rank, but that only draws attention to him. Learning from master physickers has its benefits, but there are dangers and he's not certain whether he can trust the new friends he's made. 

The A'ras of Nyaesh have a terrifying reputation: skilled swordsmen, owners of powerful magic, and ruthless killers. When they kill her parents, Carth discovers her parents had trained her for magic she never knew she possessed. She must use the skills they taught to stay alive, discover a way to find answers, and avenge them if she can. Only the discovery of a greater threat than the A'ras forces her to risk herself, for new friends and a home she never wanted.
