She Wolf Wanted by Jane B. Night

Noah Vance’s life is turned upside-down when he receives a letter asking him to become the guardian of his orphaned niece and nephews. Noah knows he can’t care for four children and run his law practice alone so he places an ad in the newspaper seeking an eligible she-wolf to wife.
Catherine Danielson arrives in Barton expecting to hand over the care of her niece and nephews to their uncle but when he begs her to remain until he can find a wife she can’t say no. She’s put her life on hold to care for the children since the death of her brother-in-law. Another few months of waiting won’t matter. It isn’t as if there is a home and husband for her to return to.
As Catherine gets to better know Noah Vance, the boarding house awaiting her return and the career-focused life of a spinster appeal to her less and less. Unfortunately, her alpha has other plans for Catherine. Plans that will destroy her dreams and ruin the life she wants to build.
