Disclaimer: I Am a long time fan of his work. Cannot recommend it highly enough. 11/10


Some excerpts

"Larry Correia .... is an unstoppable writing machine who pumps out books the size of Tom Clancy doorstoppers at least once a year, in addition to maintaining an almost daily blog, is almost omnipresent online, and has a BS tolerance threshold lower than mine."

Content warrning: "Monsters and gun violence. There may be a language warning. But I?d honestly give this to early teenagers. Granted, I read Tom Clancy novels when I was 14, so I may not be the best judge of that."

"Who is it for? Anyone who likes, fun, innovative ways to use the forces of darkness as an enemy, and new ways to approach them. Or, to paraphrase Correia himself, these books are for anyone who thinks Cujo should have been a five page short story, with three pages debating which gun to use."

"Larry Correia sets the standard for fun insane action and vivid characters."
