In the 1960's, brothers Al and John, their cousin Freddie, friends Mike and Tom attend the Royal Naval College in Dartmouth, Devon. Al and John live in a large house on the Cornish side of the River Tamar and Freddie lives on the Devon side of the Tamar. Each year Al and John's parents throw a party for the the young officers of the College, in their famous Sea Garden. Kate and Cass are friends, Cass marries Tom and Kate marries the somewhat cold Mark, who she later divorces and then marries botantical artist David. University graduate and botanical artist Jess, wins a top prize for her work, meets David's widow, Kate, and when Kate finds out that through her grandparents, Mike and Juliet, Jess has a connection to Devon/Cornwall and Kate's friends, she invites Jess down to stay with her.
The story regularly flashes back to the 1960's, to explain what happened then. Jess who looks very much like her grandmother Juliet, who was lusted after by the young College officer cadets, finds herself embroiled in family secrets and mystery, especially when invited to stay with John and his mother Rowena.
The story involves the the group of friends from the 1960's and their present day families and their relationships.
Enjoyable, however, initially I thought that too many characters were introduced and got confused and skipping back and forwards in time didn't help. I freely admit that I skipped some of it in the middle and went onto a later chapter.
