Moon has spent his life hiding what he is — a shape-shifter able to transform himself into a winged creature of flight. An orphan with only vague memories of his own kind, Moon tries to fit in among the tribes of his river valley, with mixed success. Just as Moon is once again cast out by his adopted tribe, he discovers a shape-shifter like himself... someone who seems to know exactly what he is, who promises that Moon will be welcomed into his community. What this stranger doesn't tell Moon is that his presence will tip the balance of power... that his extraordinary lineage is crucial to the colony's survival... and that his people face extinction at the hands of the dreaded Fell! Now Moon must overcome a lifetime of conditioning in order to save and himself... and his newfound kin.

All his life, Moon roamed the Three Worlds, a solitary wanderer forced to hide his true nature — until he was reunited with his own kind, the Raksura, and found a new life as consort to Jade, sister queen of the Indigo Cloud court. But now a rival court has laid claim to him, and Jade may or may not be willing to fight for him. Beset by doubts, Moon must travel in the company of strangers to a distant realm where he will finally face the forgotten secrets of his past, even as an old enemy returns with a vengeance. The Fell, a vicious race of shape-shifting predators, menaces groundlings and Raksura alike. Determined to crossbreed with the Raksura for arcane purposes, they are driven by an ancient voice that cries out from . . . .The siren depths.

A former friend has betrayed the Raksura and their groundling companions, and now the survivors must race across the Three Worlds to rescue their kidnapped family members. When Moon and Stone are sent ahead to scout, they quickly encounter an unexpected and potentially deadly ally, and decide to disobey the queens and continue the search alone. Following in a wind-ship, Jade and Malachite make an unlikely alliance of their own, until word reaches them that the Fell are massing for an attack on the Reaches, and that forces of the powerful Empire of Kish are turning against the Raksura and their groundling comrades. But there may be no time to stage a rescue, as the kidnapped Raksura discover that their captors are heading toward a mysterious destination with a stolen magical artifact that will cause more devastation for the Reaches than anything the lethal Fell can imagine. To stop them, the Raksura will have to take the ultimate risk and follow them into forbidden territory. The Harbors of the Sun, from celebrated fantasy author Martha Wells, is the thrilling follow-up to The Edge of Worlds, and the conclusion of a new Three Worlds duology of strange lands, uncanny beings, dead cities, and ancient danger.

Before Martha Wells captured the hearts of MILLIONS with her Murderbot series, there was Khat, Sagai, and Elen, and a city risen out of death and decay... The city of Charisat, a tiered monolith of the Ancients’ design, sits on the edge of the vast desert known as the Waste. Khat, a member of a humanoid race created by the Ancients to survive in the Waste, and Sagai, his human partner, are relic dealers working in the bottom tiers of society, trying to stay one step ahead of the Trade Inspectors. When Khat is hired by the all-powerful Warders to find relics believed to be part of one of the Ancients' arcane engines, he, and his party, begin unravelling the mysteries of an age-old technology. This they expected. They soon find themselves as the last line of defense between the suffering masses of Charisat and a fanatical cult, bent on unleashing an evil upon the city with an undying thirst for bone. That, they did not expect. This updated and revised edition is the author’s preferred text.

In "The Dark Earth Below," Moon and Jade face their biggest adventure yet; their first clutch. But even as Moon tries to prepare for impending fatherhood, members of the Kek village in the colony tree's roots go missing, and searching for them only leads to more mysteries as the court is stalked by an unknown enemy. Stories of Moon and the shape changers of Raksura have delighted readers for years. This world is a dangerous place full of strange mysteries, where the future can never be taken for granted and must always be fought for with wits and ingenuity, and often tooth and claw.

While running away from home for reasons that are eminently defensible, Emilie’s plans to stow away on the steamship Merry Bell and reach her cousin in the big city go awry, landing her on the wrong ship and at the beginning of a fantastic adventure. Taken under the protection of Lady Marlende, Emilie learns that the crew hopes to use the aether currents and an experimental engine, and with the assistance of Lord Engal, journey to the interior of the planet in search of Marlende’s missing father. With the ship damaged on arrival, they attempt to traverse the strange lands on their quest. But when evidence points to sabotage and they encounter the treacherous Lord Ivers, along with the strange race of the sea-lands, Emilie has to make some challenging decisions and take daring action if they are ever to reach the surface world again.
