Juliet White has only one living relative left, the child that her now deceased sister bore six years past. Juliet is an indentured servant and chooses to sell several more years of her life to her master if he will allow her to go to Scotland to look for the child. Juliet's search takes her to the home of Lachlan MacKenzie, The Duke of Ross whom she comes to believe is the child's father. However there is one problem. Actually four...four girls who are as different as any siblings could be, except for their ages. They are all six years old. Lachlan MacKenzie loves his daughters and protects them with a fierceness no one dare cross. Each having a different mother, Lachlan must protect their mothers' identities, else they could come to harm. Politics lay at the heart of the matter, and if the history of the children becomes known, many could suffer. When Juliet obtains the position of governess to the children, her secret efforts to discover their mothers' identities is as fierce as Lachlan's determination to keep the girls' past hidden. Trust must be earned on both sides before the two can allow themselves to give in to the feelings each stirs in the other. Regardless of their suspicions and distrust, Lachlan and Juliet are drawn to each other and can no longer deny their feelings. Each of the girls has claimed Juliet's heart and once she realizes that it doesn't matter which is her blood relative, as she loves them all, an enemy from Lachlan's past becomes curious about the girls and may put them all, and Lachlan's people, in grave danger.
In Scotland to locate the child her sister bore just before she died, Juliet White becomes a governess at the castle of Lachlan MacKenzie, where she fears her motherless niece is being held as one of MacKenzie's four illegitimate daughters.
