About the Book

The Caine Riordan Universe returns to finish the battle for Earth!

September 9, 2121 AD. After the failed invasion of Earth, word arrives that the Arat Kur have been defeated in their home system. For two years, humanity watched the skies, fearing that the exosapients might return.

Even before they attacked, Earth was reeling from unprecedented shocks. Caine Riordan revealed the discovery of alien ruins, the exosapient Accord contacted Earth, and the resulting multi-speciate Convocation became the pretext for invasion. All in six months.

But rather than bringing relief, the news of victory releases a hot surge of suppressed conflicts, grudges, and greed which, together, might accomplish what an alien invasion could not: the destruction of the fledgling Consolidated Terran Republic.

Two old war heroes—Ira Silverstein and David Weber—grudgingly answer the call to prevent that outcome. The first item on their agenda: investigate and defang the militant factions using post-war resentments and bigotry to advance their own agendas. And the pair certainly have their work cut out for them as they navigate the CTR’s seething tsunamis of change. Smoldering beneath Earth’s facade of unified purpose, old embers of hatred, distrust, and injustice flare.

Raves and Reviews

Praise for Charles E. Gannon:

“Chuck Gannon writes the kind of science fiction we all grew up on: rousing, mind-expanding, pulse-pounding sagas of spaceships and aliens. He’s a terrific writer, and we’re lucky to have him.” —Robert J. Sawyer

“[A] strong [writer of]…military SF…[much] action going on in his work, with a lot of physics behind it. There is a real sense of the urgency of war and the sacrifices it demands.” —Locus

Praise for Compton Crook Award-winner for best first novel Fire with Fire:

“Chuck Gannon is one of those marvelous finds—someone as comfortable with characters as he is with technology, and equally adept at providing those characters with problems to solve. Imaginative, fun, and not afraid to step on the occasional toe or gore the occasional sacred cow, his stories do not disappoint.” —David Weber

“If we meet strong aliens out there, will we suffer the fate of the Aztecs and Incas, or find the agility to survive? Gannon fizzes with ideas about the dangerous politics of first contact.” —David Brin

“The plot is intriguing and then some. Well-developed and self-consistent; intelligent readers are going to like it.” —Jerry Pournelle

“[T]he intersecting plot threads, action and well-conceived science kept those pages turning.” —SFcrowsnest

Praise for Nebula-nominated second entry Trial by Fire:

“I seriously enjoyed Trial by Fire. This one’s a tidal wave—can’t put it down. An excellent book.” —Jack McDevitt

“Gannon’s whiz-bang second Tales of the Terran Republic interstellar adventure delivers on the promise of the first (Fire with Fire)…The charm of Caine’s harrowing adventure lies in Gannon’s attention to detail, which keeps the layers of political intrigue and military action from getting too dense. The dozens of key characters, multiple theaters of operations, and various alien cultures all receive the appropriate amount of attention. The satisfying resolution is enhanced by the promise of more excitement to come in this fascinating far-future universe.” —Publishers Weekly, starred review

“[D]efinitely one to appeal to the adventure fans. Riordan is a smart hero, up against enormous obstacles and surrounded by enemies. Author Gannon does a good job of managing action and tension to keep the story moving, and the details of the worlds Riordan visits are interesting in their own right.” —Analog

“[O]ffers the type of hard science-fiction those familiar with the John Campbell era of Analog Science Fiction will remember. Gannon throws his readers into an action-packed adventure. A sequel to Fire With Fire, it is a nonstop tale filled with military science-fiction action.” —The Galveston County Daily News

Praise for Caine’s Mutiny:

“This is military Science Fiction the way it’s supposed to be written. . . . All in all, a highly satisfying tale of the Terran Republic that moves the story forward and setting us up for the next chapter, which promises to be interesting at worst and explosive at best.” —SFcrowsnest

Praise for Raising Caine:

“Raising Caine unveils a lot of thought-provoking ideas, but ultimately this is a space opera adventure. There are space battles, daring emergency landings, desperate quests, hand-to-hand combat, and double-and-triple crosses. It’s an engrossing read. You owe it to yourself to read the two previous books in order. Then enjoy Raising Caine. It’s an intergalactic thrill-ride.” —Fantasy and Science Fiction Book and Audiobook Reviews

“This is science-fiction adventure on a grand scale.” —Kirkus

“Gannon’s harrowing . . . military space opera (following Trial by Fire) builds well on his established setting . . . Gannon’s signature attention to developing realistic alien worlds makes this installment satisfying.” —Publishers Weekly

“[A]n incredibly active book . . . as our protagonists are confronted by the beautiful, terrible, and sometimes lethal variety of the universe and its inhabitants. . . . A whole mess of fun…that manages to be scientifically accurate while refraining from excessive wonkiness. Those who value meticulous worldbuilding . . . will certainly have their needs met.” —BN Sci-Fi and Fantasy Blog
