Disputed Love by Frances M Carr

It was not an easy prospect for nanny Isabelle Mendes to hand over three year old Jack Carlton to a father he had never seen. After his mother was killed in an accident it had been decided that Jack should live with his estranged father, Jeffrey, and that Isabelle, who had looked after him since birth, should personally deliver him to Northumberland. Isabelle had no reason to have any feelings for this man except anger. But he was soon throwing her emotions into turmoil.
