From New York Times Bestselling Author Wendy Corsi Staub, writing as Wendy Markham. Previously published as Slightly Engaged.

In the season of weddings, Tracey Spadolini can't help but imagine her own...
It's been a year and a half since Tracey and Jack moved in together, and everything's totally perfect—well, okay, almost perfect. There's still Tracey's mom, who says they're "living in sin," and her friends, who are smug, married and totally sure that there would already be a ring on Tracey's finger if she hadn't been in such a rush to cosign a lease. Even Tracey is beginning to wonder whether Jack really is looking for a permanent relationship, or whether she's just renting space in his heart.
But just when Tracey's doubts become overwhelming, Jack's mother lets her in on a secret—he's just taken an heirloom diamond out of the family's safe-deposit box, which must mean that he's going to propose any day now.
Okay, any week now... Any month now?
