Relic

After a raging fire consumes her town and kills her parents, Maggie Davis is on her own to protect her younger sister and survive the best she can in the Colorado town of Burning Mesa. In Maggie's world, the bones of long-extinct magical creatures such as dragons and sirens are mined and traded for their residual magical elements, and harnessing these relics' powers allows the user to wield fire, turn invisible, or heal even the worst of injuries.

Working in a local saloon, Maggie befriends the spirited showgirl Adelaide and falls for the roguish cowboy Landon. But when she proves to have a particular skill at harnessing the relics' powers, Maggie is whisked away to the glamorous hacienda of Álvar Castilla, the wealthy young relic baron who runs Burning Mesa. Though his intentions aren't always clear, Álvar trains Maggie in the world of relic magic. But when the mysterious fires reappear in their neighboring towns, Maggie must discover who is channeling relic magic for evil before it's too late.
Relic by Renee Collins is a thrilling adventure set in a wholly unique world, and a spell-binding story of love, trust, and the power of good.
