Steel Tree (Paperback or Softback)

A science fiction retelling of The Nutcracker.

Publishers Weekly says: "Ulibarri engages deeply with Tchaikovsky’s classic, studding the narrative with an imposing space-bound Christmas tree, dancing fairies, romance between Klara and her printed-circuit android prince, and a hissable villain."

The voyage from Earth to Petipa isn’t cheap, but those who can’t afford it can pay off the trip by working the farms of Eta, the fertile moon that feeds humanity’s new colony. Klara Silber’s parents paid their debt, but left her behind, in charge of the orchards and the android nutcrackers. She’s sure if she follows their example, she’ll earn her invitation to ascend the space elevator and join Petipa Colony in no time. Only, the android nutcrackers have been malfunctioning all season, and some of the other farmers have suddenly gone missing.

They were told Eta didn’t have any native animal life, but the annual winter party is abuzz with rumors of large creatures lurking in the shadows. When one of the party guests inexplicably transforms into a giant rat and goes on the attack, Klara is sure the night can’t get any stranger. That is, until a fairy-like creature who communicates through dance appears, and a whole hidden history unspools about how the humans conquered these alien lands. To prevent the nuts that caused the giant rat mutation from being sent to Petipa, Klara needs to get two very different communities to work in harmony, even if it means she may never earn her way to the colony.
