"Mallery beautifully illustrates the power of female friendship and the importance of reaching for one's dreams."—Publishers Weekly

Beloved bestselling author Susan Mallery brings readers an emotional, witty, and heartfelt story that explores the nuances of a broken family’s complex emotions as they strive to become whole in this uplifting story of human frailty and resilience.

Finley McGowan is determined that the niece she’s raising will always feel loved and wanted. Unlike how she felt after her mom left to pursue a dream of stardom, and when the grandfather who was left to raise them abandoned her and her sister, Sloane, when they needed him most. Finley reacted to her chaotic childhood by walking the straight and narrow—nose down, work hard, follow the rules.

Sloane went the other way.

Now Sloane is back, as beautiful and as damaged as ever…and she wants a relationship with her daughter. She says she’s changed, but Finley’s heart has been burned once too often for her to trust easily. But is her reluctance to forgive really about Sloane or worry over losing what she loves the most? With the help of a man who knows all too well how messy families can be, Finley will learn there’s joy in surrendering and peace in letting go.

Don't miss The Happiness Plan, a new novel coming from #1 New York Times bestselling author Susan Mallery where three women experience hope, heartache, and the power of friendship as they search for true happiness!

  • Another amazing read from Susan Mallery

    By DDJoy1969
    I can’t remember the last time I read a book all in one sitting. I loved Finley and Jericho right from the start and was determined to dislike Sloane no matter what. As usual, Susan Mallery has a way of turning everything around and showing the good in people without it being completely unrealistic and sappy. She also tackles a difficult topic with tact and insight. Don’t hesitate to pick up a copy of The Sister Effect. You won’t be disappointed!

  • Let’s Get Started on The Rest of Our Lives

    By Michelle Pierce
    I always love reading a Susan Mallery book and this is another great story but on the more serious side. I liked the characters Finley, Aubrey, Sloane, Molly, and Lester and then we have Jericho, Antonio, Gil, Lauren and Kelly, plus so many others. I really felt for Finley being put in a situation where she’s raising her sister’s daughter and is an amazing and supportive mom figure to Aubrey especially with the aftermath of what she’s still dealing with from Sloane in putting her in her current situation. Finley is finally getting her head above water and then it seems like here we go again.. She has a lot of feelings towards her family and when we find out what has gone on in the past with Sloane, her mother Molly and now her mom wants her grandfather Lester to move in, and Finley is just supposed to smile and agree knowing how they all treated her in the past. Then we have Jericho who Finley works with on his houses and he has a lot going on in his life himself between his ex-wife and his brother and his mother who just wants everyone to get a long and he isn’t on board with that at all. I loved that Finley and Jericho started a friendship and could honestly talk to each other with what was going on in their respective lives and get some advice from the other and maybe see the situation through a different perspective. Each finds out a lot more about their situations and Finley finds out that lies were told yet both Finley and Jericho are both told by family to just forgive the person and the situation, but there is a lot to forgive for both of these characters. When Sloane’s friend Ellis has an accident that is the last straw for her and her hard fought sobriety is on the line and this is when everything changes for Sloane, Finley and Jericho. Sloane definitely needed a wake up call and I wish it hadn’t happened the way it did but it put everyone in a much better place and it gave Finley the nudge that she needed to get on with her life. I appreciated the epilogue, and we were given a glimpse of where these characters are after the story ended and it was a great update. This story, in my opinion, deserves more than five stars.
  • Beautiful Story!

  • Another great Susan Mallery book

    By Jayhawk1921
    She is my “go to” author. I have been reading her books for years. She did not disappoint. The only problem is, I’ll have to wait a while for her next book.
  • Amazing read!

    By Xiaguan2014
    Susan Mallery has grown so much over the years as an author. She is never afraid to tackle tough issues and she always does it with style and grace. This book is amazing! Yes there may be triggers for some but she writes Finley and Jerichos family drama from so many points of view. I could not put this book down!
  • Another great read

    By Karen'sKorner
    Susan Mallery’s book The Sister Effect is for me another winner from one of my favorite authors. Although there were a few tough spots to read and could be triggering for someone who has had to deal with alcoholism. There is a HEA which I believe she did a wonderful job on how she wrapped up the story. I was left feeling very satisfied with the way it ended and I don’t always get that “ Oh yeah, that’s perfect” feeling when finishing a book. I seriously read this one in one day, it was hard to put down. This one is worth the read
  • Another 5 Star read.

    By ledoss
    This story hit very close to home. All worked out for these main characters, but seldom does in the real world. Loved this, with the hope that my experience will also, eventually work for the best, but hope is fleeting. Enjoy this read, another hit by Ms. Mallery.
