She and her husband were childhood sweethearts, and they're trying for a baby... Are you really going to be that despicable homewrecker?” “If it's her, then I will.” 2. [Married woman x brother] “If she remembers everything, including that you're not the husband she loves most, what will you do?” “I'll wait for her verdict.” 3. [Girlfriend x boyfriend's roommate] “Why? We've been brothers and roommates from high school through college!” “Because she likes you. Because she's your girlfriend. That's why I've always been your roommate.” 4. [Black-and-white boyfriends] “Brother, even if I can't measure up to you in anything else, she only has eyes for me.” “Then if you become a part of me, maybe she'll be able to see me too?” * The blurb is unhinged, and the story is even more unhinged. * The hero gets put through the wringer. Whether there's a happy ending depends on the story. * The hero is sexually inexperienced; the heroine may or may not be. * Respect one another and read civilly. Theme: Follow your heart
