Thank you to NetGalley and the publisher for a copy of this book in exchange for an honest review.

This was a very fun and interesting read. This will be great for kids. It is a great start to a series and I am looking forward to the next book in the series.

I liked this book I think is a good read and a nice story with a good moral lesson to teenage girls to learn.
I have a younger sister so even though I am a adult I could relate to the girls fellings and situation, so if you are a teenage girl that have sister this boo will be even more relatable.
I highly recommend to all the girls!

This book was exactly, what i needed. The feeling of being the second favourite child, or the lesser loved one, is something a lot of people can relate to.
I loved the friendship between Casey and Santana, who both found, what they needed in the other person, and made each other grow as people.
This book teaches kids the importance of communicating their feelings, either with each other or adults they trust. And that itis okay, to feel that way. I would recommend this book to every kid, whether they are the favourite child or not, because it also accurately shows the feelings of being the "neglegted" sibling.

3.5/5 ⭐️ 10 y/o read this and these are her thoughts:

I thought the story was great. The plot was a little vague in the beginning, but then it got juicer at the end. I love how Santana and Casey learned that they aren’t overshadowed, but their parents are stuck in some ways. There were little problems for the characters that weren’t necessary for the plot of the story, which distracted me. It was similar to The Babysitters Club. Overall, it was a pretty good book and I’d recommend to my friends.

The Second Favorite Daughters Club is everything I remember my childhood being like: secret clubs, annoying siblings, and struggling to make and maintain relationships. Santana and Casey come together over their love of a book series and form a club to dethrone their siblings and become the favourite daughters in their families. I was rooting for and cringing at the mistakes of both girls. This book is full of everything that makes up girlhood, and I think it shows that kids learn from mistakes and from watching their friends. I through this book was fantastic and did a really good job of touching on all of the themes it brought up, and it would make for a great read for any middle-grade girl.

I think everyone can relate to this book on some level. Not everyone understands sibling rivalries, but we all know the feelings of being overlooked. We all have experienced feelings of being leftovers or leftovers. Santana and Casey bond over the the issues that they experience with feeling like the second favorite daughter in their families, The question is does seeking revenge solve the problem. I really enjoyed this view from these girls. I enjoyed the wisdom of Casey as time went by. I love the resolution at the end, opening to a series. I will definitely plan to buy the book for my library.

I received an advance copy from NetGalley in exchange for this review.

This is a great sibling novel when two girls create a bond of friendship by sharing the same aggravation: they feel second when it comes to their sisters and decide to declare war. The lack of communication and pressure ends up leading them in the worst direction, but growing up is recognizing mistakes and taking the right measures to rectify them. They thought that war was a way to feel justice and rewarded but turns out that it wasn't. Sometimes all comes down to communication and honesty. I am glad for this book because there are plenty who relate to their situation, feeling secobd, or that no matter how hard they try it's never enough, but sometimes the other people aren't even tracking any of it, and are unaware of how one may feel.
A great and in fun contemporary middlegrade.
Thank you Netgalley and Publisher for this e-arc.

This!! Played to every emotion yet it was an absolute delight to read! I think this is the perfect little book to make us feel seen yet explore it in ways we might not have thought. Honestly I’d read this again as well. It was just too cute in some places while being devastatingly emotional in others.

This book was really good and I think that you should never ever try to do some of the things that the girls in this book did.
I didn't like that this book was kind of hard to read and it took me longer than most book to read.

Growing up in large family there was relatable elements in the ideas of Santana and Casey, definitely for a younger audience though but still enjoyable.

Santana and Casey are constantly feeling excluded from their families and both feel like their parents favor their sister over them.

I was hopeful for this book, but found it to be geared to a much younger demographic than the 7th/8th graders that I was expecting. Additionally there were many phrases throughout such as "nothing to write home about" that doesn't come off as something a middle schooler would say.

Santana has a problem with her sister Victoria; all of the family's attention is directed to the older girls' ballet career. Casey also has a problem with hers; young Sage and her father are two peas in a pod, and Casey feels excluded ever since her mother abandoned the family. The girls meet at school and bond over their sibling woes. The decide to create a Second Favorite Daughters club and even have meetings in a treehouse, since neither have a cell phone. When Cai, a cute boy in Santana's class, asks her to set him up with Victoria, Santana declares an all out war. Both girls put plans into place to make their sisters look bad, and make them look like model children. This includes wreaking havoc with Victoria's schedule by reprogramming phones and blaming Sage when Casey purposefully kills all of her father's plants. When Santana tells Cai about this plan, which she promised she would keep secret, Casey is angry. Of course, Victoria eventually finds out. After Casey's mother visits for a while but then leaves because she just can't handle being with them, Casey is angry and done with her mother, but this leads her to be more understanding of her father. Santana, on the other hand, runs away to New York City. Will the girls ever be able to figure out their place in their families?

This is a good choice for readers who like to investigate family dynamics with books like Willis' Smaller Sister, Howland's Forget-Me-Not Summer, or Palmer's Love You Like a Sister or who really like the mean spiritedness of Andelfinger's graphic novel adaptations of Pascal's Sweet Valley Twins books or Harrison's The Clique.

After Santana and Casey become friends, they find out they both feel that their sisters get all the attention and Casey and Santana are made to feel unimportant. The girls decide to form a secret club so they can sabotage their sisters. Both try to prove to parents their sisters aren’t as great as the parents think, but when Santana’s plan is found out, and her older sister gets mad and tackles her Santana runs away. What happens next?
