i give this a three to 3.5
After a tragic accident on Martha’s Vineyard, keeping secrets becomes a way of life for the Tangle family. With memories locked away, the sisters take divergent paths. Callie disappears, Mimi keeps so busy she has no time to think, and Ginger develops a lifelong aversion to risk that threatens the relationships she holds most dear.

When a whispered comment overheard by her rebellious teenage daughter forces Ginger to reveal a long-held family secret, the Tangles’ carefully constructed web of lies begins to unravel. Upon the death of Glory, the family’s colorful matriarch, and the return of long-estranged Callie, Ginger resolves to return to Martha’s Vineyard and piece together what really happened on that calamitous day when a shadow fell over four sun-kissed siblings playing at the shore. Along with Ginger’s newfound understanding come the keys to reconciliation: with her mother, with her sisters, and with her daughter.

At turns heartbreaking, humorous, and hopeful, Sisters One, Two, Three explores not only the consequences of secrets—even secrets kept out of love—but also the courage it takes to speak the truth, to forgive, and to let go.

i had mixed feeling about this book. I did not like Glory at all; was annoyed with Ginger's relationship with her husband and daughter, thought we maybe did not get enough information about Julia growing up to understand why she rebelled against her mother. Then just when I was really disliking the book, the last quarter of it started pulling things together, giving it a purpose and explaining somewhat why everyone was the way they were. I think a read is still going to have parts they dislike, parts of the story not totally pulled together, etc. But still a worthwhile read and lots there for group discussion!
