I'm sure y'all have seen PJ Hoover's former cover of her novel, Solstice, previously self-published.
Now that Tor is re-releasing it under their banner in 2013, Solstice has gotten another fabulously fiery cover:
Piper's world is dying. Each day brings hotter temperatures and heat bubbles that threaten to destroy the earth. Amid this global heating crisis, Piper lives under the oppressive rule of her mother, who suffocates her even more than the weather does. Everything changes on her eighteenth birthday, when her mother is called away on a mysterious errand and Piper seizes her first opportunity for freedom.
Piper discovers a universe she never knew existed—a sphere of gods and monsters—and realizes that her world is not the only one in crisis. While gods battle for control of the Underworld, Piper’s life spirals out of control as she struggles to find the answer to the secret that has been kept from her since birth.
An imaginative melding of mythology and dystopia, Solstice is the first YA novel by talented newcomer P. J. Hoover.
