You Make Me Happy by Mimi Barbour

Jocelyn grudgingly takes time off from renovating her kitchen and accepts the sweet older couple’s invitation for dinner. Unexpectedly, she meets their suave investment banker son and decides he is an enigma from anyone she’s met before. Out of her element, she can’t seem to get her head on straight, be herself and stop acting weird. While helping in the kitchen, she ends up witnessing Ethel in the throes of an excruciating headache and is baffled when the older woman refuses to call out for her husband. She admits they’re planning on operating within a few weeks and doesn’t want her worrywart hubby to find out until closer to the date. “His fussing will drive me batty.”
Jocelyn sympathizes but stays firm. “Fine, then tell your son… or I will.”
Bruce has always depended on his mom to be there in his corner. When he finds out he might lose her, his world turns upside down. It’s their new neighbor from across the street who holds him together. Correction – she supports all of them in her warm, gentle way as the big day approaches.
