Critics Review

Praise for To Tread Obsidian Shores: “An unconventional work of military sci-fi set during peacetime … Cordova and Olthoff still delivers the fighting esprit de corps and noble sacrifice common to wartime stories… . The emotional sting of loss and comforts of companionship are fairly distributed, and a late surprise revelation sets things up nicely for book two. Military SF fans will find it hits the spot.” —Publishers WeeklyPraise for Jason Cordova: “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 “Jason Cordova is the master of the blasters-and-spaceships style SF that I grew up on, a throwback to a classic era of space adventure … From kaiju to mecha, from bounty hunters to mercenaries, Cordova has done it all and done it well.” —Rick Partlow, best-selling author of the Drop Troopers seriesPraise for Melissa Olthoff: “… 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 “Olthoff’s veteran experience shines through in the authenticity of her character interactions and dynamics. She knows what it’s like to drive yourself to the breaking point in order to keep your brothers- and sisters-in-arms alive … and it shows.” —Kacey Ezell, USAF Retired, coauthor of The Romanov Reign series

About The Author

Jason Cordova

Jason Cordova is a John W. Campbell Award and Dragon Award finalist. He edited his first anthology, Chicks in Tank Tops, coauthored Monster Hunter Memoirs: 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.

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 first 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.
