Mail Order Mommy (Boom Town Brides)

A Mother by Christmas 

Nursing a broken heart, Amanda Porter had answered a frontier mail-order bride ad placed by Garrett Decker's children—only to find the groom-to-be didn't want a wife. The widowed bachelor she hoped to marry does need a housekeeper, though, and taking the job is Amanda's only option. But his adorable children are determined she'll be their mother by Christmas… 

His wife's betrayal and tragic death demolished Garrett's life. Now he can't even look at another woman, let alone marry Amanda, who resembles his first love. Even if she does make his house feel like a home, filling it again with laughter and his children's smiles. But with his daughter convinced Amanda is the perfect mother, will Garrett realize she's also his perfect match?
