Fill In The Blank: Some Feelings Weren't In The Fine Print

She can become anyone a room needs. The problem is, he may be the first person who wants her as herself. Addy has built a career out of being exactly who strangers need her to be. As the founder of Fill in the Blank, she provides stand-ins for life's awkward moments: a distant cousin at a funeral, a supportive friend at a wedding, a colleague at a corporate event, the missing piece in a room full of expectations.
She is polished, prepared, emotionally unflappable, and very clear about one rule. No romantic partner jobs. Caleb Navarro is not looking for romance. He is looking for survival. Every summer, his loud, loving, relentless family gathers at a Michigan lake house, and every summer Caleb arrives alone. This year, tired of being lovingly interrogated about his nonexistent love life, he books a fake girlfriend through Fill in the Blank.
Due to one very inconvenient administrative error, Addy arrives not as Caleb's girlfriend, but as Jennifer, his long-lost half-sister. Somehow, that makes everything worse. Now Addy must charm Caleb's suspicious sister, survive his perceptive grandmother, dodge an aunt with dangerous levels of enthusiasm, and maintain a fake family history while spending a long weekend beside the one man who sees through her professional calm a little too easily.
Caleb expected backup. He did not expect Addy. Addy expected a job. She did not expect lake-house chaos, family warmth, inconvenient chemistry, or the terrifying possibility that the role she is least prepared to play is herself. Smart, funny, tender, and full of dry banter, Fill in the Blank is a slow-burn romantic comedy about found family, fake identities, emotional honesty, and the dangerous business of being seen.
