The Sorrows The Sorrows by Jonathan Janz

What do you do if you own an island off the coast of northern California that has been uninhabited since a series of gruesome murders occurred there in 1925? Well, when two film composers say they'd pay good money to stay there because they want to be inspired to write the score for a new horror film—you say yes. Only after composers Ben, Eddie, and their friends get to Castle Blackwood do they come to realize that an evil force resides there, trapped for nearly a century. And now it's ready to feed.

Dragon's Code Dragon's Code by Gigi McCaffrey

SF/F Grand Master Anne McCaffrey's Dragonriders of Pern series is a fan favorite. Set on a far-off planet colonized by humans in the distant past, humans ride telepathic dragons to protect the world from the ever-present threat of Thread, a lethal space-borne spore that rains destruction from the sky. In honor of the fiftieth anniversary of the first Pern story, Anne's daughter, Gigi, has picked up the mantle of telling stories in this fascinating world. In Dragon's Code, the balance of power on Pern hangs in the balance after the long dormant Thread returns and, for the first time, dragons are on the verge of fighting other dragons.

Archenemies Archenemies by Marissa Meyer

Archenemies continues the story by New York Times-bestselling author Marissa Meyer begun last year with Renegades. The set-up is that the so-called Renegades, a rogue syndicate of prodigies (humans with extraordinary abilities) emerged from the ruins of a collapsed society to restore order. Against this backdrop is the ill-fated relationship between Nova, a super-villain who seeks revenge against the Renegades, and Adrian, who is a Renegade himself. In Archenemies, Nova is leading a double life, maintaining two covers: one as Insomnia, a Renegade who possess power over sleep, and another as Nightmare, a villain determined to destroy the Renegades. But Nova's feelings for Adrian could foil her plans.

Those who drink the demonic booze see terrible things—like the destruction of Long Island itself in fire and flood. It's up to Ellie and a visiting socialite to stop this supernatural menace.
