Call of the Dark :

A GIFT SHE NEVER WANTED. A MAN SHE CAN’T RESIST. A WAR THAT COULD TEAR THEM APART. Anna Walker has always kept her unique ability hidden: she can step inside the dreams of others. But when a close friend falls into a mysterious coma, Anna’s desperate attempt to help thrusts her into a nightmare of angels, demons, and ancient prophecies. A fallen angel demands she recover the Horn of Gabriel. A heavenly counterpart hires her to do the same. Torn between good and evil, Anna uncovers a terrifying truth—her family’s prophecy names her the Keeper of the Holy Relics, the only one who can stop the coming war between Heaven and Hell. NARRATED BY THE AUTHOR. Perfect for fans of Kim Harrison, Ilona Andrews, and Lara Croft–style adventure.
