Almost Time for Cover Reveal

I still don't quite understand when a cover reveal should happen. The cover for Frank at Heart, #6 of the Foothills Pride series, was finalized this weekend, but the book doesn't release until the end of May.

So should I be showing the cover now--or wait until the beginning of May? Or maybe when it's available for preorder?

Here's what Frank's about:

Everything about thirty-five-year-old Stone Acres hardware store owner Frank McCord is old-fashioned—from his bow tie and overalls to the way he happily makes house calls to his dreams of lasting romance, true love, and marriage. Frank’s predecessors have run the store and been mainstays in the small California town for over a century. While genial Frank upholds tradition and earns the respect of friends and neighbors, he fears he’s too dull and old to attract a husband.

Into his life comes handsome thirty-six-year-old electronic games designer Christopher Darling and his fifteen-year-old son, Henry. Christopher has everything Frank could want in a potential partner: charm, kindness, and compatibility. Also, he’s a terrific father to Henry. When their Stone Acres home turns out to be uninhabitable, Frank offers the Darlings temporary lodging in his ancestral farmhouse, where he and his tenant Emil reside. Since Emil thinks Frank is his, sparks fly. Suddenly, Frank’s monotonous life promises to explode with love and threatens to change him forever.
