Surviving the Eclipse — W.J. May

You are the key to either ending the war or starting a new one. Vampires, witches, and humans alike can feel a storm brewing. A civil war is on the horizon. It's believed that vampire covens are teaming up to lead an attack on Sanlow. Almost twenty years ago, the vampire-run city that kept humans as slaves was decimated by a single merciless vampire named Amate, who abolished the blood cattle system. Half-vampire, half-witch Bastian Hayes is haunted by the mystery of who his parents were—until it is unraveled in a dangerous encounter with his half-sister, who reveals a shocking truth: they share a father. A father who, as it turns out, is one of the powerful, ruthless coven leaders of Sanlow.  As the reality of his parentage brings new, more powerful enemies, Bastian learns of a rumor that a strange event could allow a vampire to walk in the daylight—the only time humans are safe. An eclipse is the opportune moment for vampires to mount a full-scale assault on Sanlow to reclaim it from Amate and reinstate the system. Meanwhile, the notorious spellbook Bastian was entrusted to safeguard has been stolen. He and the Kairos—the vampire-hunting revolutionary organization—must locate it before it lands in the wrong hands and sparks a catastrophic war.   Cursed is the man who dies, but the evil done by him survives.. Dusk to Dawn SeriesPrequel: Enchanted - Book of SpellsBook 1 - Awakening the NightBook 2 - Surviving the EclipseBook 3 - Hunting the Forsaken
