Help Me With Some Book Recommendations: For A Non-believer And For An Sda

Friends: Please help me some good book recommendations here. 1–for a single man, who has “played the field” for years and wants to settle down, but is a non-believer;
2–for an SDA, totally ingrained in such, spouse a former Catholic;
3–for an older person who has never taken a stand for their faith;

Thx friends so much!!!. I do think the best way to get good book recommendations is from another person. One very good recommendation I got was for Scott Hahn’s book “A Father Who Keeps His Promises”–for the single man above. I feel though, unfortunately, this is just too intellectual and scholarly for this gentleman. Perhaps another recommendation? more simple? would be awesome.
