After everything is destroyed by the Fall, Charlie embarks on an incredible search for God’s renewed embrace. He travels from one biblical story to the next, uncovering surprising connections in God’s great story. But he is also tested at home. As doctors fight for his daughter’s life, Charlie tries to prove his innocence in the accident and save his marriage.

Curriculum Vitae
David Hollenstein went to school in Zollikofen, north of Bern, Switzerland. He completed a commercial apprenticeship in the fiduciary industry and then got a taste of the media air in the accounting department of a large news agency. After attending several Adonia music camps as a teenager, David, then 20, accepted a position at Adonia in Brittnau. After his first year as an intern, he worked for several years in the shipping department, as a project manager of the music camps for families and later for children (Adonia-Junior), as a product manager, radio play director, and editor of the children's program "Schere, Stei, Papier" on Radio Life Channel.
During this time, David studied practical theology, married, and started a family with four children. After over 20 years with Adonia, Hollenstein oversees the publishing program, is responsible for editorial and marketing, and serves on the board of directors.
Becoming an author
In his school days, writing, dictation, and spelling were not David's strong points. Reading was not one of his regular hobbies either. But stories played an early role when he and his brothers made short films on free school afternoons. Writing first caught David's attention when he passed his apprenticeship exam with the highest letter writing/written communication grade. He went on to study practical theology. This included submitting written work regularly. His classmates complained about the writing, while David enjoyed it. One of these papers became his first book, "Ich liebe dich! Ich liebe mich!" (Adonia Verlag).
As editor of Adonia's youth magazine "Take-it", he began writing short radio plays (e.g., "The Diary of Jennifer Braun"). This led Adonia to create a complete radio play bible for children. David Hollenstein was responsible for the project and wrote half of the stories. When Adonia took over the radio play tradition of the former "ERF Radio Plays", David Hollenstein also began to write other radio plays. Among other things, this resulted in the series Jan & Co.
David Hollenstein developed a true passion for writing books and radio plays in the following years.
