For MMGM, I'm recommending Ghosts by Raina Telgemeier.
Here's the publisher's description:
Raina Telgemeier has masterfully created a moving and insightful story about the power of family and friendship, and how it gives us the courage to do what we never thought possible.
Firstly: ART! ART! ART! ART! ART! In other words, Ghosts is a graphic novel, just like Telgemeier's other books (such as Smile, a super-popular graphic novel which you should also read). The art is beautiful, and captures the town in the book, Bahía de la Luna, incredibly well as a foggy ocean town (for a completely fabulous image, see pages 22-23). The story is as great as the art. Telgemeier has always been both a great artist and writer, and Ghosts is no different. Cat's sister, Maya, suffers from cystic fibrosis, and Telgemeier handles it very well, especially with worries about the possibility of Maya dying. The characters are very well-written, and both Cat's nervousness about Maya and Maya's ability to stay happy are very realistic. In addition, as you might have guessed from the title, there are ghosts in the book, and they tie into the theme of Día de los Muertos, or Day of the Dead, a Mexican holiday which is less about mourning and more about celebrating those who have died. The description of this holiday is great, and the visuals for the related festival are great, featuring great color by Braden Lamb, the book's colorist. This book does everything fabulously and is a great read.
