Why Read This?The one-sentence sell. What do you get for showing up to this book, even when it's hard?

A military sci-fi that earns its emotional punches through characters you genuinely root for. The romance is woven into the fabric of the story rather than bolted on, with two veteran authors who balance action and heart perfectly.

Synopsis

WHAT DOES IT MEAN TO BE A WARRIOR? The Protectorate of Mars Foreign A path to citizenship. A fresh start. Defending the Protectorate of Mars against all enemies, foreign and domestic. HOPE With itchy feet and a vagabond soul, all Blue ever wanted was to join the Survey Corps and explore the universe. But when she failed the entry exam, becoming a dropship pilot for the Legion was her last chance at achieving that dream. It was only supposed to be a stepping stone . . . DUTY All he ever wanted was a home. But when Tavi is driven from his world by murderous revolutionaries, he only has one chance to the Legion. Searching for a new life, he soon discovers something even better—a family. WELCOME TO THE LEGION At the publisher's request, this title is sold without DRM (Digital Rights Management). Jason Cordova is both a John W. Campbell Award and Dragon Award finalist. He edited his first anthology, Chicks in Tank Tops , coauthored Monster Hunter Fever with Larry Correia, and wrote Mountain of Fire in the Black Tide Rising universe, all with Baen Books. He has 28 novels currently in print and has been featured in numerous anthologies. A Navy veteran, he is also a former middle school teacher. Though Californian by birth, he has since relocated to the South, where he swears at the humidity on a thrice-daily basis. He can be found at www.jasoncordova.com. Melissa Olthoff . is a science fiction and fantasy author who delights in sneaking in romance wherever she can. She is a lifelong geek and a veteran of the United States Air Force, both of which are incredibly useful when writing. Her degrees in meteorology and accounting are slightly less applicable to writing but absolutely useful when it comes to supporting her family. In 2023, she took second place in the annual Baen Fantasy Adventure Award Contest with her story “Fall from Grace” and won the Imadjinn Award Best Short Story in 2023 and 2024. She is published by Baen, Chris Kennedy Publishing, Hit World Press, and Three Ravens Publishing, and is best known for her novel of the Griffin Corps, Rise from Ruin , and novels in the Four Horsemen Universe, the Blood & Armor Series, the Salvage Title Universe, and Hit World Valkyries, as well as numerous short stories. Praise for Melissa “. . . Olthoff creates not only a believable and immersive world, but populates it with people whom you can respect, understand, care for, and sometimes want to punch in the face . . .” —Jody Lynn Nye, New York Times best-selling author Praise for Jason “A great combination of story-telling skill and imagination that really hooks you.” —Larry Correia, New York Time best-selling author of Monster Hunters International
