The concept was very interesting, people serving the lord and that are not able to die. They just live forever. They can get hurt or sick but they heal quickly. I was glad David found out that there were more people like him, all saved by the same serum from the same doctor. I loved that he collected books and owned a book store. I was glad he told his assistant Tiana about his living forever. Nice work of speculative fiction. Overall a solid three star book for me. I do not usually read Christian fiction. I have some friends who might enjoy this one whom I plan to recommend this book to them. Some parts were slow but it did pick up once he found the others like him. The writing is nice. The character development is great.
