Of Gold and Greed by Chanda Hahn

High in goblin infested mountains lies the ruins of Ter Dell, the lost stronghold of the dwarves. Evil lurks beneath layers of ice and broken stone, buried in a vault of gold, hungering for the day that man’s greed would see it unearthed.
That day has come.
For I am Rheanon, one of the adoptive daughters of Lady Eville—and I’m trapped in a web of deceit with the King’s deadly blades-enchanted beings that guard the king and hunt those with magic.
Beset by enemies, I must use my gift of alchemy to forge a sentient blade with ancient knowledge and a sharp edge. I needed a powerful weapon. I got a giant pain in the axe.
