Dwarves of Calcus is the third installment of the Fairytale Galaxy Chronicles

When she was thirteen, Snow Sabbia crash landed on the dwarves' home planet of Calcus. After fleeing from her step-mother's huntsman, seven brother dwarves took her in to hide and protect her. She has hidden for years on the peaceful planet, tinkering with old automobiles and pushing papers in the mine office.
Then, Timothy White shows up.
The shy, nervous, nerdy heir captivates Snow before she even knows who he is, and quickly she falls in love. But his high profile in society draws unwanted attention from her vengeful stepmother, who wants Snow dead.
Geneva believed Snow died years earlier and she had consumed her innocent heart. With her late husband's wealth, Snow's inheritance, in tow, she married a young lord, Conrad. Both are using each other--Geneva for his title and to have a child, Conrad for her money and beauty. But when Conrad lays eyes on his boyhood rival's lovely fiance, Snow, his overwhelming desire for her reveals the truth to Geneva, that Snow lives.
Desperate to hold onto her wealth and power, Geneva seeks to kill Snow properly this time. Snow has the power to wield the one thing that can destroy her, so she cannot let the girl claim possession of the family heirloom, the Nevollo Sword. 
Snow soon learns her step-mother knows she is alive. But she is a pacifist, so she must outwit Geneva and remain hidden... until Geneva, disguised as a child, presents her with an apple.

ABOUT THE SERIES

In a small galaxy far, far, away, magic thrives in all its varieties. Elves, dwarves, ogres, leprechauns, all exist on their planets, but they rely on one source for their magic; human emotions. Humans rule the two vast kingdoms that vie for dominion, Oran and Tyrone. Within these kingdoms, three great families have blossomed into power; the Whites, the Diamontes, and the descendants of sirens.
With each book retelling a different fairy tale and linking the characters known and beloved by many together, The Fairytale Galaxy Chronicles reveals the history and legend of the heroes and heroines, villains and the fallen, as three fairies witness them all.
