"For a long time she simply stood there, finding herself traveling back to the time the instrument was given to her. The feeling of his hands on her face when he covered her eyes as he had led her into the spare room... The smile of total satisfaction that had crossed his lips the minute he told her to open her eyes and look upon her gift. Her heart jumping in surprise when she saw it... His words came back to her. 'This is something of my own creation for you alone.'..." It seems that Isabelle's faith is always being tested. Though blessed in many ways, she has been robbed of the most basic thing anyone could want: a normal life. And, to Isabelle, having to endure such an existence could only be one thing: a punishment for a great, unknown sin. Sent to help her through her pain, however, is Caleb, the guardian angel unexpectedly charged with watching over her life. Over the years, their bond deepens, developing into the true love that Isabelle believed impossible for her to find. But when demons, disciples of Satan, begin waging attacks on Isabelle, Caleb, and their friends, their newfound happiness is destroyed as the two are sent on a trying, whirlwind journey that puts everything to the ultimate test, as they strive to keep their memories and move forward into the future, including their strength, their love, and even their faith.
