Searching for a book I saw in a Facebook Post possibly comedy/ humor about an atheist whose life is complicated by an angel

[Laura]

I recently saw this book about an atheist whose life is made complicated by an angel who lives on his ceiling and acts as his conscience with unpredictable and humorous results on a Facebook post, sadly I forgot to add it to my post collection of things I want to order. I don't remember the title, author, or publisher all I can remember is the above summary. Any help is appreciated. I also know is probably a fairly recent book that probably was published between 2020 and this year.

Does anything on the Atheist Fiction list look familiar?
