From the description at amazon.com:

David Brin's Uplift novels--Sundiver, Hugo award winner The Uplift War, and Hugo and Nebula winner Startide Rising--are among the most thrilling and extraordinary science fiction tales ever written.  Now David Brin returns to this future universe for a new Uplift trilogy, packed with adventure, passion and wit.

The planet Jijo is forbidden to settlers, its ecology protected by guardians of the Five Galaxies.  But over the centuries it has been resettled, populated by refugees of six intelligent races.  Together they have woven a new society in the wilderness, drawn together by their fear of Judgment Day, when the Five Galaxies will discover their illegal colony.  Then a strange starship arrives on Jijo.  Does it bring the long-dreaded judgment, or worse--a band of criminals willing to destroy the six races of Jijo in order to cover their own crimes?

Book Three in the Uplift Storm Trilogy

The peaceful existence of six outcast races on Jijo has ended. Ancient enemies, the Jophur, have discovered them, preparing to subject the refugees to their dark, perverted plans.

The Jijoans’ only hope is the same ship that accidently led their foes to the planet. The Earthship Streaker, with its crew of uplifted dolphins and a human commander, must somehow lure the Jophur into a chase through space . . . into the unknown. And then into the weird.

More than just the fate of Jijo—or that of distant Earth, also suffering a deadly siege—hangs in the balance. Some believe a terrifying prophecy is about to come true, one that involves Streaker’s trove of artifacts coveted by factions throughout all Five Galaxies. As countless white dwarf stars verge on unexpected explosion, all sentient life in the universe appears to be at risk unless someone can save them.

A once peaceful planet of refugees faces complete annihilation in this hard science fiction sequel to Brightness Reef.

Book Two in the Uplift Storm Trilogy

It’s illegal to occupy the planet Jijo, but six castaway races have managed to coexist there for some time. They’ve successfully hidden from watchful law enforcers of the Five Galaxies—until now . . .

After making an amazing discovery far away—a derelict armada whose mere existence triggered interstellar war—the Terran exploration vessel Streaker and its crew of humans and dolphins arrive at Jijo in search of sanctuary from the Galactic forces out to destroy them.

But they were followed. As behemoth Galactic starships descend upon Jijo, heroic—and terrifying—choices must be made. Together, human and alien settlers must choose whether to fight the invaders or join them. The crew of the Streaker, meanwhile, discovers something that just might save Jijo and its inhabitants . . . or destroy every last one of them.

“Well paced, immensely complex, highly literate . . . Superior SF.” —Publishers Weekly, starred review

THE
PRACTICE
EFFECT
by David Brin

Physicist Dennis Nuel's career has taken a sudden and startling turn.  After being denied access to the Zievatron Project through the political machinations of his chief rival, the self-righteous, priggish Bernald Brady, Dennis is needed back - badly.  The zievatron, a device created to provide access to parallel worlds, has indeed made contact.  But now the return mechanism is malfunctioning, and the only way to repair it is for someone to go through to this alien world where no human has yet ventured.  That some-one is to be Dennis Nuel.  He will also take with him the tiny, flying, pig-like creature he's dubbed a "pixolet" (because it looks like a cross between a pixie and a piglet) to return the little alien to its homeland.

Only after Dennis has stepped into the air lock, with the door about to close, does Brady mysteriously hint that they've discovered something strange on the other side, something

different about the other world's physical laws. But before Dennis can question Brady, the door swings shut.

Stepping through the door into this new world, Dennis discovers to his horror that the return mechanism isn't malfunctioning - it's been vandalized.  Instead of mere repairs, he has a complete job of reconstruction on his hands!

The search for the materials and technology he needs to make the repairs takes Dennis on a journey that will introduce him to the Coylians, people who are quite human and speak a recognizable form of English, but whose culture is disconcertingly different from any on Earth.  Coylian society is based on "The Practice Effect," the anomalous physics Brady hinted at.  The Coylians need not make implements and clothes.  Rather, they "practice" goods into perfection.  Primitive instruments of flint and twigs are practiced into gleaming tools; rough garments are worn and practiced into silks and brocades; huts are practiced into the soaring buildings of a tiered city.

Dennis wants only to return home, but he soon finds himself entangled with the ruthless political schemer, Kremer, in his plot to take over. Dennis is to be Kremer's secret weapon in his conquest of the world.

Aided by a clever thief, a plucky little exploration robot, the irrepressible pixolet, and the beautiful L'Toff Princess Linnora, Dennis must combine the science of Earth with his still nascent ability to "practice" if he is to vanquish the formidable Kremer and repair the zievatron in order to return home.

A starship crew of humans and dolphins skirts the brink of interstellar war in this epic adventure by the New York Times–bestselling author of The Postman.

We are not alone. Humanity’s explorations have revealed galaxies inhabited by millions of intelligent species interacting under ancient traditions. Foremost among said traditions is uplift, which requires all spacefaring races to welcome newcomers into Galactic culture by breeding and genetically guiding each client species to full sapience—but at a price. Patron races demand centuries of indentured servitude from each uplifted client. But is upstart humanity a patron or a client?

The Earthship Streaker—crewed by humans and uplifted dolphins and chimpanzees—discovers a derelict armada, perhaps left by the very first patrons, the fabled Progenitors. Suddenly the Five Galaxies teeter on the brink of all-out war as fanatics hunt Streaker for the secret. With a damaged ship and hostile aliens in pursuit, the crew must band together if they hope to survive . . .

This ebook features a new introduction by the author.

From amazon.com:

David Brin's Uplift novels are among the most thrilling and extraordinary science fiction ever written.  Sundiver, Startide Rising, and The Uplift War--a New York Times bestseller--together make up one of the most beloved sagas of all time.  Brin's tales are set in a future universe in which no species can reach sentience without being "uplifted" by a patron race.  But the greatest mystery of all remains unsolved: who uplifted humankind?

As galactic armadas clash in quest of the ancient fleet of the Progenitors, a brutal alien race seizes the dying planet of Garth.  The various uplifted inhabitants of Garth must battle their overlords or face ultimate extinction.  At stake is the existence of Terran society and Earth, and the fate of the entire Five Galaxies.  Sweeping, brilliantly crafted, inventive and dramatic, The Uplift War is an unforgettable story of adventure and wonder from one of today's science fiction greats.
