As a cartography student, Jak has always dreamed of finding the lost dragon gate and exploring and mapping distant worlds. Developing magical powers and becoming a powerful wizard? Not a chance. But when he and his archaeologist mother unearth the gate, they attract the attention of the very wizards they sought to avoid. Even more troubling, Jak starts developing magical powers of his own, powers that could rival those of the great rulers.

I’m Val Thorvald, and I’m an assassin. When magical bad guys hurt people, I take care of them. Permanently. This doesn’t make me popular with the rest of the magical community — as you can tell from the numerous break-ins and assassination attempts I’ve endured over the years. But thanks to my half-elven blood, a powerful sword named Chopper, and a telepathic tiger with an attitude, I’ve always been able to handle my problems with aplomb. Maybe some cursing and swearing, too, but definitely aplomb.

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.

Imperial law enforcer Amaranthe Lokdon is good at her job: She can deter thieves and pacify thugs, if not with a blade, then by toppling an eight-foot pile of coffee canisters onto their heads. But when ravaged bodies show up on the waterfront, an arson covers up human sacrifices, and a powerful business coalition plots to kill the emperor, she feels a tad overwhelmed. Worse, Sicarius, the empire's most notorious assassin, is in town. He's tied in with the chaos somehow, but Amaranthe would be a fool to cross his path. Unfortunately, her superiors order her to hunt him down.

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.

After helping my steady dragon Zav with his family problems, I thought life would get back to normal. As normal as it can be when you’re a hit woman responsible for hunting down bad guys. That was before a strange artifact showed up in a bog and turned my ancient dwarven sword into a magical beacon. Now, my enemies can sense it from hundreds of miles away. Usually, fighting off opportunists wouldn’t be a problem (they don’t call me Ruin Bringer without reason), but even I can only handle so many attacks at a time.

She’s happy renovating homes and occasionally thumping bad guys until she learns of a mysterious artifact hidden under the house she’s working on. Everybody from humans to orcs to werewolves wants it, and they’re willing to kill to get it. Things go from bad to worse when someone frames her for murder.

As a bookish, introverted database programmer, Morgen Keller never thought she was a candidate for a midlife crisis. That was before her husband divorced her, her boss let her go, and her grandmother died. Forty wasn’t supposed to look like this. When Morgen heads up to the small town of Bellrock, Washington, to settle the estate, she looks forward to taking a peaceful break from life and figuring out what she’s going to do next. But peace isn’t to be had.

Arwen Forester may be a socially awkward introvert, but she’s an expert tracker, archer, and forager who has a pickling recipe for every vegetable in the garden. Unfortunately, none of these skills earn her a lot of money. And when the taxes go up on her father’s farm, she’s not sure how to help him keep the property. Then someone offers her a lucrative new gig: Hunt down a haughty half-dragon criminal with the power to incinerate those who irritate him.

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.
