Mom Overboard [EPUB ebook] 

Famous novelist Dorothy Ackerman invites her estranged daughter, Rachel, on a four-day cruise to Bermuda to coincide with Mother’s Day and the girl’s 25th birthday. The trip should be a relaxing vacation and bonding opportunity for them. But they’re barely speaking. Both women have ulterior motives for going on the cruise together, and they try to get what they need from each other. A handsome stranger acts as kindling to ignite old grudges and distrust between the Ackermans. By the end of the trip, the two women disembark with a greater understanding of each other and themselves.
