(none of which are written by me or any of my friends)
Out of the Black, by Lee Doty
A fast-paced, violent blend of police mystery, science fiction, and horror, rife with plot turns and flashbacks, this book grabbed me from my first look into the heads of the unconventional main characters. If you liked Guillermo Del Toro's The Strain, you'll like this.
Pay Me, Bug!, by Christopher Wright
Space opera at its finest, with a crew of charming miscreants, well-paced plot, and dialog so snappy it'll make you snort milk through your nose. If you liked Bujold's Vorkosigan books, you'll like this.
In Hero Years, I'm Dead, by Michael Stackpole
Comic-book noir, where larger-than-life heroes with feet of clay and closets full of emotional baggage do battle with the forces of indifference and entropy as well as more tangible villains. If you liked Grossman's Soon I Will Be Invincible, you'll like this.
Bait Dog, by Chuck Wendig
Atlanta Burns may be a YA heroine, but her world is as mean as they come. Emotionally charged and viscerally violent, this is not a book for the faint of heart, but it will make you cry, swear, and cheer out loud. If you liked The Girl With the Dragon Tattoo, you'll like this.
