In the third and final book in the middle grade series that Newbery Honor winner Rita Williams-Garcia raved is “brimming with hilarity and sisterly hijinks,” Marigold, Zinnia, and Lily Silver return to Cape Cod for another unforgettable summer.
The Silver Sisters are heading to Pruet again to visit their Aunt Sunny, now-uncle Tony, and the rest of the friends they’ve made on Cape Cod over the past two years. This summer, Pruet is turning 300, and the town is planning a huge celebration. And on their first day back East, the sisters make a promise they hope will make this the best summer no fighting.
It shouldn’t be too hard. Each sister, after all, has her own focus during the visit. Marigold makes it her mission to befriend Chloe, the famous director Philip Rathbone’s niece, who is working on the set of her uncle’s upcoming project. Zinnie is busy creating an attention-grabbing blog to help her chances of becoming editor-in-chief of her school’s literary journal. And Lily has become quite the explorer with her science day camp group. All seems to be going smoothly until Zinnie’s growing friendship with Chloe leaves Marigold feeling hurt. Once again, her little sister has intruded on her life.
With the divide between the girls growing deeper, Marigold, Zinnie, and Lily worry it’s impossible for them to go a summer without a big fight. The same silver moon may hang in the night sky each year, but the sisters below it are changing in ways they have yet to understand. If they grow apart, more than a promise could be at risk. But if they grow together…the sky is the limit.

The Silver Sisters are back in Pruet for another unforgettable summer! Marigold, Lily, and Zinnie are visiting Aunt Sunny, Uncle Tom, and all of the other friends they have made while in Pruet. This summer, the town is turning 300 years old, so the town is celebrating by hosting a tricentennial. To make this summer even more interesting, the sisters made a promise at the beginning of vacation...no fighting! Since everyone has a focus this summer, they believe it shouldn't be too hard. Marigold is hoping to befriend Philip Rathbone's niece whom will be attending the same school as her come fall. Zinnie is busy trying to impress her school with an amazing blog! Lily has become a natural explorer and scientist because of the Science Day Camp she has been attending. But soon, Marigold feels betrayed by Zinnie when Rathbone's niece seems to like Zinnie more than her. The summer looks rough for the girls, but can they pull it together and still make it the most unforgettable summer ever?
This was cute as was the second and first. The book isn't very exciting anymore because we know where they are going, and who they are seeing, and it just doesn't seem fresh. I wouldn't say it's like deja vu, but it's close. There was a kiss in the first book, no kiss in the second book, and then...God only knows how many in this book! They are children and all they care about are boyfriends and kisses. Also, the fact that Lily was smarter than the two older sisters made Zinnie and Marigold look stupid. I mean, Marigold wasn't the best character for me, so making her look stupid gave me more reason to dislike her. The relationships in this book confused me so much. They might as well be 8 years old with their first crushes, not knowing what a boyfriend is. Overall, I didn't like it. I liked the second one the most and this one the least. QUESTIONS: So, Lindsey just disappeared? Is Zinnie the editor of her school journal? How old was Lily in this book because she sounded very smart in this book? What happened with Pilar and the handbag from the last book?
If I could rate this book one hundred stars, I would. I have a Harry Potter and Warriors obsession, but other than that, this series is my number one favorite series of all time. I am SOOOOO disappointed that this is the last book in the series. I think that there should be Silver Sisters books about the other season as well. I recommend this book for all ages. I loved it so much, and I think you will too!!!;)
I wasn't sure about this series when I started it. The first book was sweet but not terribly substantial, and didn't challenge its more simplistic assumptions.
By the third book, the Silver sisters have grown and matured, and I'm happy to report that the stories have, too. Characters and themes are more nuanced. Other reviewers were annoyed by the girls' crushes, but girls aren't less deep because they become interested in romance, and I thought it was really nice to see a story that was so determined to explore first crushes in such a healthy, realistic way. The sisters have more sibling conflicts to struggle with, but they're more grounded and the girls have gotten better at honest communication. They want to be kind to each other while wrestling with anger at things that seem really unfair. And Lily has a lot more screen time, which I think benefits the story. It's a slow arc, but the lovely setting and true-to-life emotional beats pulled me forward without ever boring me. My main complaint is that Peter is lacking a lot as a crush-partner for Marigold, and I wish we'd acknowledged that more. He's not a bad kid by any means, but he seems to be mostly in his own head, while she's bending over backwards to try to sooth his feelings at all times. This is a pretty common dynamic in adult relationships and I wish we'd pushed back a bit in this story to show girls that while it's normal for other people to make mistakes and have messy feelings, being paired up with another person doesn't mean that their moods are now your responsibility.
Once again, the setting is gorgeous if a bit too idyllic, and we certainly aren't here to tackle any profound social issues. But the experiences of children and teenagers are treated with respect by the adults around them. Zinnie's passion for writing, interpreted through a blog this time around, is a serious story element encouraged by her parents and aunt. Speaking of which, emotionally healthy adults? We seem to have several of them! Particularly Aunt Sunny, who is a fantastic listener, intervenes on behalf of her nieces, makes rules when necessary, is never punitive or harsh, and is willing to change for their sakes. Great example of an adult knowing how to create safety and give guidance without dominating or assuming the worst. The moral of this story, if there is one, is that it's good to let yourself have feelings. That feelings aren't shameful, wrong, or embarrassing. In a world where young girls are so often made to feel weak for caring, for crying, for wanting, I LOVED this. The girls have to learn how to deal with those feelings in appropriate ways that don't cause harm, but stifling the feelings and ignoring them is not the answer. Great stuff.
Also! This book gets serious props from me for perhaps THE most consensual, realistic, charming, down-to-earth, believably-awkward-but-still-nice first kiss between middle schoolers that I've ever seen. I'm not much of a romantic, but children absolutely deserve models for early romance beyond "and then somehow we were just kissing I guess" or "and then one of us kissed the other and then ran away or freaked out or asked retroactive permission once it was already too late," which is what I see in 99% of even the most socially aware contemporary middle grade fiction. We had real consent in this book, people! This is not a drill!

The Sliver sisters are back in this third installment of the Silver series. And this time they have more to learn about each other and themselves than they ever thought possible.
While the sisters are helping with the town of Pruet's 300th birthday, Marigold is hoping to put her past friendship troubles behind when she meets the niece of movie star director Philip Rathbone. But when it becomes clear that Chloe is more interested in being friends with her little sister Zinne, Marigold is heartbroken. Meanwhile Zinne is determined to become editor in chief of her school's literary journal if she can blow it out of the water with her summer blog posts. As the silver moon above them wanes and changes, these three sisters will have to try and put their differences aside if they ever want the town's big birthday celebration to succeed.
This is the third book in the Silver Sisters series. The Silver Sisters (Marigold, Zinnia, and Lily) are back in Pruet, Massachusetts visiting their beloved Aunt Sunny. This summer is exciting because Pruet is celebrating its tricentennial so they get to help with the planning. The summer is also special because Aunt Sunny takes the girls on Marigold's "Fun 14th" which is a camping trip tradition to celebrate turning 14.
This coming-of-age book celebrates sisterhood, friendship, family, and to be yourself. This series is probably good for ages 8-12. The only thing my daughter and I didn't like was the super long sentences. 4/5
I would like to thank Netgalley and the publisher for providing me with an audio ARC.
This is another fun read in this series. I really enjoyed how this series has tackled growing up and struggles and anxieties that young readers often have. The sisters are all easy to relate to and I was happy to see a little more focus on Lily in this book. I do still love that there is a lot of emphasis on Marigold's point of view where she can seem like she is shallow, but really is worried about not having any friends. Zinnia is also flawed in similar ways to Marigold as well and I enjoy the balance is shown. I also love the narrator foe this book and it really feels she does an excellent job portraying all the characters.
I love these books and I'm so sad that this is the last one. It's been so much fun to revisit the Silver sisters and Pruet every summer. They have all grown up so much and I'll miss not knowing what they're doing next summer. Is it to much to hope for an update set a few years in the future, maybe for Lily's fun fourteenth?
The Silver Moon of Summer is the final book in the Silver Sisters series. The Pruet setting is still nice, but I didn't find the plot the most engaging here, and Marigold and Zinnie started to get annoying. I wish Lily had been given her own chapters! Howland also continues to overuse "said" and to use "spaz" as an insult, which goes unchallenged.
If you have ever had jealousy with a sister or sibling over someone like I have, you will find this book very realistic. It is a great story and sisterhood is the main take away from this story. I love how they change perspective because then you can understand how each sister is feeling. I love all the books in this series and recommend this book to anyone with or without siblings.
I'm so sad this trilogy has ended! I absolutely love the Silver sisters and their story and adventures are so inspiring. I definitely identify with Lilly (the scientist) and Zinnie (the writer) the most!
Great addition to this series. I love that each of the girls is developing her own identity in the family. The conflict is still there between the older sisters but they are also growing into their own space.
5 stars to this book and the series as a whole. Loved every minute with the Silver sisters, their Aunt Sunny, and all the wonderful characters in Pruet on Cape Cod! Will miss them, but it's best to end on a high note!
This is a feel good book about a family who goes on vacation. The siblings learn that boys and friends will come and go but sisters stay forever. The book proves that with loyal sisters and not so loyal friends. Very elementary themes and situations. Grades 3-5. Optional Purchase.
I really liked this book! I love that Zinnia showed her feelings for Max, and that they kissed. I wish Chloe would have told Marigold herself that she didn’t really poke hanging out with her but that’s okay. I could easily see these books being turned into movies.
This entire review has been hidden because of spoilers.
As much as I loved the first two books in the series, I found this one to be lacking in the same amount charm and heart. The two older sisters seem whiny and obsessed by boys. I just lost interest.
