The book is a single mother mc romance. I cannot remember the title or author.
Plot points I remember are the mom walks up to the club house with a bat after an mc member, not the mmc, get into a fight with her baby’s father in front of her daughter.
Also the little girl hides in the cellar of her father’s house when men come to kidnap her. Then the mom gets in a cop car thinking he is taking her to the station but kidnaps her instead.
