The Companion by Chelsea Hale

Mandy Jones goes at life alone. At least since her grandma passed away a decade ago. Wishing she could have fulfilled her grandma’s dream to travel more, she runs a successful business being a tour guide and companion for senior citizens who want to see the world. Her world revolves around connecting to her grandma’s generation.

Derek Thompson took over as CEO when his grandfather passed away. Trying desperately to prove himself to the world, he works long hours, dedicated to the legacy his grandfather left behind. When his grandma, Alice, decides to hire a travel companion, Derek just knows she’s being scammed, and joins Alice on a two-week trip to prove he’s right.

Sparks fly when Derek and Mandy meet. The cruise ship is not big enough to hold the annoyance between them. It will take several sea days to realize that both of their lifestyles are more similar than different, as they hide from their past and from their future.
