Captain Telryn “Trip” Yert is on the most important mission of his life. Accompanied by Captain Kaika, the sentient soulblade Jaxi, and Rysha Ravenwood - the noble-born scholar and officer he definitely shouldn’t be developing feelings for - he must find a way to close a portal that’s allowing more and more dragons into the world. If he fails, all of humanity could fall to the powerful creatures. As if that wasn’t enough to worry about, the secret Trip has spent his whole life hiding, that he can draw upon magical power, is on the verge of being discovered. 

Now that Trip’s siblings are safely back in the capital, he would like it if life got back to normal. As normal as possible for a half-dragon army officer learning to use his magical powers when he isn’t busy piloting with Wolf Squadron. But trouble keeps popping up, and the capital isn’t the safe haven Trip had hoped. More and more dragons are working together, with attacks growing frequent as they scheme to claim the country for themselves. 

Telryn "Trip" Yert has always been a little odd, with hunches that are too accurate to explain. Magic is feared and forbidden in Iskandia, so he's struggled his whole life to hide his eccentricities. As a boy, he was forced to watch his mother's execution. Her crime? Witchcraft. Understandably, Trip wants nothing to do with the power that lurks within him, always threatening to reveal itself. Instead, he dedicates himself to serving as an officer in the king's army, to battling pirates and imperial conquerors. He longs to become a soldier as respected and renowned as General Zirkander.

A mission to a foreign land has left Captain Trip Yert with a responsibility he never anticipated: watching over two dozen magical stasis chambers containing half-dragon young, including eight that are half-human. As bewildering as he finds it, all of them are related to him. He’s vowed to ensure they make it safely back to his homeland where the sorceress Sardelle can, he hopes, advise him on how to care for them. But while he, Rysha, and Major Kaika are investigating a friend’s death and trying to arrange passage home, someone steals one of the baby girls.

General Ridgewalker Zirkander is getting married. Sardelle - the woman who’s battled dragons, shamans, and countless enemy soldiers at his side - has accepted his proposal, and it’s the perfect time for a wedding. It’s been two months since any dragons or sorceresses attacked the city, the Cofah haven’t come after their kidnapped emperor, and King Angulus has stopped yelling at Ridge for his inadvertent role in destroying the castle.

Everyone knows dragons have been extinct for over 1,000 years. Everyone is wrong. At least one dragon remains, and military scientists from the Cofah Empire are experimenting with its blood, using the magical substance to power deadly new weapons that could be used to bring the world to its knees. That's a concern for Zirkander, Cas, and the rest of the Iskandians, but all Tolemek wants is to find his missing sister.

It's been a week since the dragon Morishtomaric fell, and Sardelle is not convinced that Ridge is truly gone. With a companion who thinks he's a god and a soldier who would happily kill her, she heads back to the mountains to look for signs that Ridge survived. What they uncover threatens to destroy their country and all they care about.

A thousand years have passed since a dragon has been seen in the world. Science and technology have replaced magic, which has dwindled until it has become little more than an element of myth and legend. There are those who still have dragon blood flowing through their veins, distant descendants of the mighty creatures of old. These rare humans have the power to cast magic, the power to heal, and the power to craft alchemical weapons capable of starting wars...or ending them.

Responsible for her friend's death, Lieutenant Caslin Ahn wants nothing more than to be left alone. She no longer deserves the company of comrades or the fulfillment she felt as a Wolf Squadron fighter pilot. But a summons from the king leaves her with no choice but to rejoin her teammates. An ancient evil has been unleashed, bringing death and destruction to the nation, and they are the only ones with a chance of stopping it.

Ridge, Sardelle, and their comrades may have rescued Tolemek's sister and freed the dragon, but trouble awaits at home. The king is missing, a secret organization is hunting sorcerers, and the capital is more vulnerable than ever to enemy attack. Worst of all, at least from Ridge's point of view, someone put that jackass Colonel Therrik in charge of the flier battalion.

Professor Lilah Zirkander is looking forward to a summer in the paleontology lab, researching and cataloging new fossils. But that summer takes an unexpected turn when the king sends her into the Ice Blades to a secret mine where ancient dragon bones have been discovered. Rumor has it that they're cursed and dangerous, but Lilah is more concerned about dealing with the outpost commander, a fierce officer with the temperament of a crabby badger.

Captain Astuawilda Kaika is an elite forces soldier, a demolitions expert, and a woman who loves secret missions. She most certainly isn't someone with the patience to teach General Zirkander's raw cadets how to survive encounters with the enemy. Certain she's been given this duty as a punishment, she confronts her superiors, only to find out that King Angulus himself gave her the assignment.

All Sergeant Evrial Yara wanted was to protect the young emperor from those plotting to kill him. Joining forces with a group of notorious outlaws wasn’t part of the plan, especially not when one of them is determined to charm her out of her uniform at every turn. Working with the criminals might have been worth it if their efforts had saved the emperor, but it seems he’s not the rightful heir to the throne...Evrial may have thrown away her career for nothing. To make matters worse, fate isn’t going to give her time to calmly decide what to do next.

The greatest military leader of his time. The most talented code breaker her people have. Sworn enemies. When deadly secrets from the ancient past are unearthed, secrets capable of fracturing the world and destroying all life on the planet, these two enemies will have to work together. They are humanity's only hope.

Crown Agent Jev Dharrow’s good dwarf friend Cutter is missing, as is the city’s master gem cutter. Jev doesn’t know who would want them, but he’s determined to find out. He hopes his fellow agent, Zenia, can help him locate the missing dwarves. Even though she rejected his offer of a romantic relationship because of their status differences, they have become good friends, and she has years of experience finding criminals. But this kidnapping is anything but simple. Jev and Zenia find themselves entangled in a snarled plot that threatens the entire kingdom while making them realize their true feelings for each other.
