Summary: Darynn, Fyra, and Kaylaa have solved the mysteries of the gods. But how can they unveil the secrets to save the starving Olan-Har without unleashing chaos upon Vastire? Even if they knew what to do, war with long-time adversary Erodia forces them to wait. Unfortunately, the Erodians are winning: they’ve taken Vastire’s capital and bombard the west coast nightly. With few options left, Commander Aseus turns to Darynn to attempt a daring mission to infiltrate Erodia, just like his grandfather did 80 years ago. With Fyra, Kaylaa, and a small team at his side, Darynn agrees to the treacherous mission across the dangerous, wild continent filled with powerful enemies. But he’s conflicted. Not only does magical power rampage within, but he starts to wonder who he’s fighting for: royalty and the clergy, or the people? That question will drive him to make impossible choices. If he chooses correctly, he can end the war and save the Olan-Har, but at a great cost. If he doesn’t, the Erodians will rule Vastire and the secrets of the gods will be lost.

Summary: Queer Handmaid's Tale meets hyper-capitalist dystopia. Nonbinary, queer main character BREEDER is set in a distant but bleakly familiar future, where each person exists to repay Units to the violent Corporation. But girls and women can only be Breeders in this world, and can only repay the Corporation through reproduction. Is the price of survival worth the cost of submission? Will Meadows is a seemingly average fifteen-year-old Westie, who lives and works in Zone F, the run-down outermost ring of the Corporation. In the future state of the Corp, a person’s value comes down to productivity: the right actions win units, the wrong ones lose them. If Will is unlucky and goes into unit debt, there’s only one place to go: the Rator. But for Zone F Breeders, things are much worse—they’re born into debt and can only accrue units through reproduction. Every day in Zone F is a struggle, especially for Will who is fighting against time for access to an illegal medical drug, Crystal 8. Under the cover of night, Will travels to the Gray Zone, where life is less regulated and drugs—and people—are exchanged for gold. There, Will meets Rob, a corrupt member of the Corporation running a Breeder smuggling operation. Will also meets Alex, another teen whom he quickly recognizes as a Breeder in disguise. Suddenly, Will has an illicit job and money, access to Crystal, and a real friend. As the pair grows closer, Alex shares her secret: she is part of the Response, an uprising to overthrow the Corporation. Caught up in the new friendship, Will and Alex become careless as the two covertly travel into Zone B for a day of adventure. Nothing goes as planned and Will’s greatest fear is realized. Will his true identity be revealed?

Summary: Harper Cody used to worry about the SATs or a getting a new laptop for Christmas… but now, she only wants to keep her little sister alive. At 5:59 a.m. early in September, life as she knew it came to an end with a nuclear flash ninety miles away in Colorado Springs. For two months, her family sheltered in the basement of their home, surviving on whatever canned goods Dad could scavenge. Passing evacuees told of a safe haven in the mountains, but her father refused to leave. He thought their home was safe… until a gang of looters kicked in the door. Four years ago at thirteen, Harper won trophies for competition shooting, but killing a man pointing a gun at her is nothing like nailing targets at a range. Hesitation cost her parents’ lives. With no other options, she grabbed her little sister and ran away from the only home she’d ever known into a world she no longer recognized. The promise of safety in Evergreen gives her hope, but unless the girl voted sweetest in her class can find the nerve to kill, Harper—and her kid sister—are as good as dead.
