Eric Dunning was only twelve and in the last six months had watched his mother Erica waste away with cancer, eight years after the death of his father Jack in the early months of fighting in Afghanistan. Torn away from everything he has ever known, a happy southern California life with his mother and his best friend April, he is sent to the complete opposite side of the country to live with an aunt and cousin he has never met. Enduring one trauma after another, circumstances alter the way he sees life, God, and himself in ways he could never have imagined.

Set against the backdrop of rural northern New Hampshire in the 2010s, Lost Faith combines elements of coming-of-age, transformation, self-discovery, and romance, interwoven with a potential answer to the question, "Why does a loving God allow good people to suffer?" It is written as a companion story to the novel, Every Day is Your Last.
