“Fast-paced, funny, and wholly entertaining, this is a must-read for fans of Rick Riordan.” —Kirkus Reviews (starred review)

The Last Dragon on Mars meets Persian mythology in this action-packed sci-fi fantasy space adventure about a boy fighting to save his planet after making a pact with an ancient demon that snuffs out their sun.

After leaving Earth, Rostam Zamini had just managed to make friends and gotten used to life on Enceladus—one of Saturn’s many moons—only to once again have to move when one of his moms gets a fancy new job on dusty and dull Pars-1. Thanks to the technology of Wishing—using djinn to power high-speed space travel—Rostam reaches his new home much sooner than he would have liked.

None of the Pars-1 kids seem to be impressed with Rostam’s big-city background. In desperate need of some space cred, Rostam makes a deal with Zahhak—a centuries-old demon prince—for popularity in exchange for the golden mace described in The Persian Book of Kings.

But when Rostam hands the mace over, he unknowingly plunges the planet into darkness by accidentally killing their ancient sun, a red giant. Now he must right his wrongs and save his new home before it’s too late.
