Never Give Up by Anne Carol

Love never fails.
The final book of the Faithfully Yours series begins as English guitarist David Somers and his California-bred wife Beth celebrate ten years together. Their anniversary comes on the heels of a big move from England to California. Leaving his years of band life behind, David—now a father of two—decides to pursue a solo music career in Los Angeles.
Beth is thrilled to return to her home state and immediately enrolls at a local university, determined to finish her writing degree. Meanwhile, David struggles to adjust to life in his adopted country, and when his music career is hampered by unexpected health issues, he gradually descends into a dark place where even Beth cannot seem to reach him. As married life spirals out of control, this young family becomes desperate for a miracle.
Just when things seem hopeless, a friend steps in with a powerful message that could rescue the Somers from a crushing downfall. Will evil win out and succeed in destroying their family, or will David and Beth renew their commitment, never giving up hope for restoration?
