Every harvest moon, the Witch Collector rides into our valley and leads one of us to the home of the immortal Frost King, to remain forever. Today is that day—Collecting Day. But he will not come for me. I, Raina Bloodgood, have lived in this village for twenty-four years, and for twenty-four years he has passed me by. His mistake.

Raina Bloodgood has one desire: kill the Frost King and the Witch Collector who stole her sister. On Collecting Day, she means to exact murderous revenge, but a more sinister threat sets fire to her world. Rising from the ashes is the Collector, Alexus Thibault, the man she vowed to slay and the only person who can help save her sister.

Thrust into an age-old story of ice, fire, and ancient gods, Raina must abandon vengeance and aid the Witch Collector in saving the Frost King or let their empire—and her sister—fall into enemy hands. But the lines between good and evil blur, and Raina has more to lose than she imagined. What is she to do when the Witch Collector is no longer the villain who stole her sister, but the hero who’s stealing her heart?

Axiom's End is an extraordinary debut from Hugo finalist and video essayist Lindsay Ellis. Truth is a human right. It's fall 2007. A well-timed leak has revealed that the US government might have engaged in first contact. Cora Sabino is doing everything she can to avoid the whole mess, since the force driving the controversy is her whistleblower father. Even though Cora hasn't spoken to him in years, his celebrity has caught the attention of the press, the Internet, the paparazzi, and the government—and with him in hiding, that attention is on her.

She neither knows nor cares whether her father's leaks are a hoax, and wants nothing to do with him—until she learns just how deeply entrenched her family is in the cover-up, and that an extraterrestrial presence has been on Earth for decades. Realizing the extent to which both she and the public have been lied to, she sets out to gather as much information as she can, and finds that the best way for her to uncover the truth is not as a whistleblower, but as an intermediary.

The alien presence has been completely uncommunicative until she convinces one of them that she can act as their interpreter, becoming the first and only human vessel of communication. Their otherworldly connection will change everything she thought she knew about being human—and could unleash a force more sinister than she ever imagined.

While the Iskat Empire has long dominated the system through treaties and political alliances, several planets, including Thea, have begun to chafe under Iskat's rule. When tragedy befalls Imperial Prince Taam, his Thean widower, Jainan, is rushed into an arranged marriage with Taam's cousin, the disreputable Kiem, in a bid to keep the rising hostilities between the two worlds under control.

But when it comes to light that Prince Taam's death may not have been an accident, and that Jainan himself may be a suspect, the unlikely pair must overcome their misgivings and learn to trust one another as they navigate the perils of the Iskat court, try to solve a murder, and prevent an interplanetary war… all while dealing with their growing feelings for each other.
