Path to the Key (Destruction of Magic #1)

Magic is fading throughout the world and the supernatural realms can feel the strain growing daily, but Sarah doesn't care about any of that. She cares about protecting her son from her vampiric ex-husband who is obsessed with gaining power. She'll stop at nothing to ensure that Alex doesn't get his hands on Jackson, even if it means welcoming more vampires and other supernatural beings into her life.
Their journey takes her across the country, seeking the help of a witch that has invaded her son's dreams.  A vampire named Zander threatens to bring all of her carefully constructed walls crashing down. She'll break every rule and every preconceived notion they have about her, as long as she can save her son and give him the future that was stolen from her. Sarah's path connects to the very battle that she tries to avoid, and when she embraces not only her growing power, but also her destiny- she might be able to change the tides of fate.
