Where’s the safest place to keep your deepest secrets?

After a summer school teacher threatens to contact her parents over a concerning personal narrative assignment, sixth grader Annamarie Nilsson vows to only write her secrets in a diary.

Sincerely Diary was a joy to read! I couldn't put it down and it even made me cry--marks of a great story! I loved the characters--not only of Annamarie but also Diary, who had quirks of its own that I was not expecting! I loved seeing Annamarie come into her own in the face of difficulties with humility and maturity. A great and empowering read!

What a fun book!

From the back cover: Annamarie Nilsson vows to only write her secrets in a diary. Secrets like wanting a best friend. And envying her dad's favoritism of her younger sister. And the fact that she's been spying on the neighbor girl who buries things in the creek. What Annamarie doesn't expect is that her diary can write back to her!

I love the imaginative premise of this story. What if a diary could write back? What would it say? The book is written entirely in diary entries written back and forth between Annamarie and Diary, and this fun format makes Sincerely, Diary a quick, engaging read. The adorable illustrations sprinkled throughout add to the reading experience, too. As a reader, I was rooting for Annamarie throughout the story, and I think young readers will as well.

I sat down with this book and read it in one afternoon. I cared about Annamarie and her quest to find friends and was intrigued by the sentient diary, as well as the other mysteries and twists that unfurl as the story goes on. As someone who wrote in diaries a lot in adolescence, I found the confessions about friends, boys, secrets, and adventures relatable and nostalgic. But I also appreciated how the book handles some heavier topics, from imperfect family dynamics to counseling to chronic illness, in gentle and age-appropriate ways. Young and more mature middle grade readers alike will find a lot to enjoy in "Sincerely, Diary."

Written entirely in diary entries makes this book a fun and quick read. It brought back many memories of the struggles and fears of being in 6th grade. Kids will definitely relate. The author nailed the main character's fun, youthful voice and gave the diary a very distinct, older voice also. The tension mounting is obvious to the reader but not to the main character, which I think kids will enjoy. The author sprinkled humor throughout to lighten the mood and kept the tone from becoming too serious. Enjoyable read.
