Quicksilver--Book 1:

Do not touch the sword. Do not turn the key. Do not open the gate.

Saeris Fane is good at keeping secrets. No one knows about the strange alchemical powers she possesses, or the fact that she has been stealing from the Undying Queen for most of her twenty-four years. But a secret is like a knot. Sooner or later, it’s bound to come undone.

When Saeris is caught stealing something she shouldn’t, she accidentally reopens a dormant gateway between realms and is whisked away to a land of ice and snow. There, she discovers that the Fae—creatures of legend and nightmare—are not only real, but they are caught up in a centuries-long conflict that might just get her killed.

After inadvertently binding herself to a secretive and incredibly powerful Fae warrior named Kingfisher, Saeris quickly learns that he will use her secret magic to protect his people, no matter what it costs him… or her.

Be careful of the deals you make, dear child. The devil is in the details... 

Brimstone--Book 2:

Duty. Blood. Honor. Power.

Saeris Fane never asked for power, but as the newly crowned ruler of the vampire court, she’s discovering that sometimes even queens don’t get what they want.

Saeris is desperately needed back in Zilvaren, but the recent changes that have strengthened her have also made her weak. With no reprieve from its punishing suns, the realm she once called home will likely kill her if she returns. Saeris must send someone in her stead…but does falling for Fisher mean that she can trust him?

Kingfisher of the Ajun Gate has defeated armies and survived hell, but this might just be the death of him. With a mysterious curse crippling Yvelia, the last thing Fisher wants to do is leave his lands and his people, but he made Saeris a promise—a promise he now intends to keep.

As darkness falls across Yvelia, Saeris and Fisher must pass through fire and brimstone to save both their realms and the people they love.
