In one book, a woman moves from a big city to a small town. She's accompanied by her mother figure (a grandmother who pretty much raised her) and the nieces and nephews she's just adopted after her sister died. She's very good at her job and ends up helping save the police force through elaborate outreach and community participation. The house needs repairs, which the love interest is happy to do. The love interest is also very good with the newly adopted children. He happens to be the police chief.
In the other, a woman moves from the big city to a small town. She's accompanied by her mother figure (the foster mother who pretty much raised her) and the niece she has just adopted after her sister died. She's very good at her job and ends up helping save the town through elaborate outreach and community participation. The house needs repairs, which the love interest is happy to do. The love interest is also very good with the newly adopted child. The other main character's love interests happens to be the sheriff.
And… in the first book, the main character is Daisy and one of her adopted daughters is Grace. In the second book, the main character is Grace and her adopted daughter is Daisy.
Crazy!
They were published close enough together that I don't see how this could be anything but total coincidence.
But despite the similarities, these were very different books, so it just goes to show that you can make a premise (or even an entire story) your own.
