Jumia Books Seven Days in June by Tia Williams

When Shane and Eva meet unexpectedly at a literary event, sparks fly, raising not only their past buried traumas, but the eyebrows of New York's Black literati. What no one knows is that twenty years earlier, teenage Eva and Shane spent one crazy, torrid week madly in love. They may be pretending that everything is fine now, but they can't deny their chemistry - or the fact that they've been secretly writing to each other in their books ever since.
