This question puzzled me at first, because it took me a while to any Christian romances which had an official “first date” scene. Most seem to have the couple meet and spend time together in normal life, rather than in the context of an official date.
They may be thrown together by work, through another character (e.g. a child if one is a parent) or through a crime (especially in romantic suspense). They spend time together, and the relationship develops from there.
This seems more natural to me than the official “date”, which often feels contrived and doomed to failure. (A view which might be affected by the number of characters in Christian fiction who are dating the wrong person!)
But then I remembered True Devotion by Dee Henderson.
Here’s the Amazon description:
Kelly Jacobs has already paid the ultimate price of loving a warrior; she has the folded flag and the grateful thanks of a nation to prove it. Navy SEAL Joe “Bear” Baker can’t ask her to accept that risk again—even though he loves her. But the man responsible for her husband’s death is back; closer than either of them realize. Kelly is in danger, and Joe may not get there in time.
(That’s not the cover on my paperback version. I don’t much like my cover, but I like it better than this cover.)
True Devotion is a slow-build romance between long-time friends, and the first date doesn’t happen until around halfway through the book. But it’s worth waiting for: Joe wants to make it a memorable occasion, but only has three hours to organise the date. He calls a bunch of favours and gets a window table at the classiest restaurant in town, and even manages to buy Kelly flowers and a bear (which is a bit of a pun, as Joe’s SEAL nickname is Bear).
