For MMGM, I am recommending The Year of the Book, written by Andrea Cheng and illustrated by Abigail Halpin.
Here's the publisher's description:
In Chinese, peng you means friend. But in any language, all Anna knows for certain is that friendship is complicated.
When Anna needs company, she turns to her books. Whether traveling through A Wrinkle in Time, or peering over My Side of the Mountain, books provide what real life cannot—constant companionship and insight into her changing world.
Books, however, can’t tell Anna how to find a true friend. She’ll have to discover that on her own. In the tradition of classics like Maud Hart Lovelace’s Betsy-Tacy books and Eleanor Estes’ One Hundred Dresses, this novel subtly explores what it takes to make friends and what it means to be one.
I really enjoyed this book! Although it is aimed more towards the younger end of the middle grade spectrum, it can be appreciated by anyone of any age. One focus of the book is on friendship, as Anna makes a new friend and copes with her friend Laura's befriending of two popular kids who aren't particularly nice to anyone, including Laura. Anna's family, particularly her mother, struggles with acclimating to the United States after immigrating from China. Anna is often embarrassed by her mother's struggles with English and job cleaning apartments as she goes to college. Laura also has family struggles, as her parents often fight, and her father often breaks things and has been kicked out of the house. The Year of the Book is a very enjoyable read, and Anna, despite making many mistakes, is a likable protagonist and narrator. All in all, The Year of the Book is a great read that discusses many important topics (and has several sequels)!
