In Whisper, Callie Evans discovered she was an Arc -a special-ops angel sent to Earth to fight the Darks that prey on teens. In Wake, book two of the trilogy, Callie was charged with the responsibility of waking up the world and preparing an army of humans to fight the battle of the ages - Armageddon. Now, in the third and last installment of the Whisper Series, Callie Evans and her team of Last Days Saints must navigate Armageddon with its Judgments and its trials, slaying demons and saving as many souls as they can before the world stops spinning. But, Callie has plans of her own, plans that include finding a way into Hell to track down the mighty Romuel and rescue him from wicked Deyanna. She's not sure how she's going to make it into Hell and even less sure how she'll escape once she gets there and finds Rom, but she's determined to bring back the ginormous angel who saved her life. It's the end of the world. Are you ready?
