Her Billionaire Co-Nanny by Shanna Delaney

This summer nanny job just got complicated.

Emma has been slowly working her way through college, determined to graduate with her independence and finances intact. Her new job as a summer nanny to the ultra-wealthy could make all the difference.
Richard manages international relations for his family’s massive candy company, and coming back to the family’s New Hampshire lake house for the summer is like coming home. But this time the house contains more than just family—his sister has brought along a nanny. A cute nanny.
When circumstances pull Richard’s sister back to the West Coast, Richard and Emma agree to share responsibility for the kids.
As attraction flares, Emma and Richard have to face their differences and decide: Is this just a summer sizzle, or can they each change perspective enough to make whatever’s between them last?
