July in Houston, Texas, is far too hot for Frost Giants. But when a Valkyrie with an attitude shows up on Marti Keller's doorstep in the middle of summer, things take a turn for the polar. After Marti returned home from her ordeal at the hands of a notorious drug and human trafficker, she had expected her life to return to its normal placid state, maybe with the addition of a splash of romance. Instead, she finds she's hopped out of the frying pan and into the Arctic Circle, where she lands square in the middle of an ancient apocalyptic prophecy. Can a tiny tweak of the prophecy change the fate of the world? She'll find out, if she lives long enough to make it to Ragnorak.

If Sarah Reeves was a faery instead of a human, it would be a whole lot easier for her to get what she wants: to ride Cheval Bayard in an elite competition; to earn a spot on the Mundane Intervention Team; and for Brendan Greenwood to like her. But Regan, her archrival at the stables is doing everything she can to steal Cheval Bayard out from under Sarah. There are more students than spaces for the Mundane Intervention Team, and competition is fierce. And Brendan inexplicably likes mean-girl Dahlia. It's enough to make Sarah wonder if she should leave the realm of Faerie and return to the Mundane world, where she might feel like less of a freak. After all, she seems to be the one person who is painfully ordinary in a place where everyone and everything is magic. But when she and her friends stumble upon a terrifying conspiracy, her humanity may be the only thing that can save both worlds.

"I didn't believe in ghosts, not until I became one." In Earthbound, by Artemis Greenleaf, Schuyler Ramsey just wants to be like the other kids in school. Too bad she's dead. She haunts a farm in windswept western Ireland, along with some of its previous inhabitants. When she partially materializes in front of her sister at breakfast, she is propelled on a quest to stop a fake TV psychic and ghost hunter from visiting the farm and stirring up trouble. Along the way, she visits a famous pirate, helps a mermaid rescue a basking shark from fishermen, and encounters Nicniven, queen of the dark elphs. But Schuyler soon finds that the Haunted Planet television show is the least of her problems. As her world unravels, can she find the strength to save her sister from a monstrous terror? Some of the proceeds of this book benefit shark conservation. See artemisgreenleaf.com for details.
