Summer of Love by Susan X Meagher
Despite their political and social views, Mary Frances Fitzpatrick and Courtney Ashcroft strike up a friendship. Courtney's sympathetic, encouraging, and genuinely concerned with Mary Frances's plight. She's so interested in gay rights, it almost seems personal. But that has to be wishful thinking on Mary Frances's part. Or does it? In Chicago, during that steamy, unpredictable summer of love, improbable dreams can, and do come true.
