Fia Brithin is beginning an adventure. On her first visit to the King Hanor's palace, 16 year old Fia Brithin stumbles into a court intrigue. To keep the secret safe, the Chancelor sends her off as apprentice to a famous, and reclusive, high mountain jeweler. ...And straight into adventure. Discovering gems with deep secrets and new friends with the same, Fia learns a whole lot more than just modeling wax. When to trust a stranger, and when not to; why not to try stealing from gem thieves; what heroism is, what royalty ought to be, and that the mountains themselves can sometimes be the greatest danger of all. The first in a series, Jeweler's Apprentice introduces protagonist Fia Brithin to the wide, wide world, and starts her on a journey toward adventures, and that difficult thing called growing up.

When the loyalist cause enlists the mountain house into a weaponry, apprentice Fia is confronted with three refugee children, a disturbingly upstart former messenger, and accidents happening everywhere. Are saboteurs out to nix the weapons works... or is it the incognito crown prince they're after? Traitor's Knife continues where Jeweler's Apprentice ended, and nearly seventeen year old Fia Brithin from the foothills still has a lot to learn about the mountains, and the people now in them.

With her wealth of loyalist secrets, Fia’s position at Olayin House is compromised. Now a potential danger to two countries, she is made a ward of the king and sent away yet again; this time into the grassland kingdom of Erlandia, but her journey amongst the horse folk takes unexpected turns. Trapped under siege she faces two men from her past... one she fears might murder her, and the other may die of plague unless she wins the battle for his life. And with the Sunlight Stone traded for troops, how long will Erlandia’s peace last?
