This third installment of the popular graphic novel series focuses on winter. While those of us who live in snow-filled areas will probably be quick to relate to some of what he describes, others from warmer, sunnier climes might not be able to do so. While I liked it well enough to finish it, I wish that it had tackled some issues and been more than a series of vignettes about going to school during cold weather and building up to a big fight between two neighborhood groups. It started out promising enough with Greg Heffley, the protagonist, musing on the possibilities of global warming and climate change and expressing some concerns about his future in that environmentally-changed world, but most of it is about building a snow fort, filling it with supplies, and then protecting their structure. As often happens in these sorts of situations, Greg and his friend Rowley and their crew must even contend with betrayal from an unlikely source. I could feel the frustration, annoyance, and determination to stick it out even while things were taking a turn for the worse, and young readers will be amused to see their favorite characters working together to fend off those intruders. But any sort of meltdown isn't really present in the book or within the plot, and even the family pig, which disappears early on, is never found, which troubled me even though Greg insists that the animal has found its way to a warmer location and is quite content. All in all, this one left me slightly amused but also disappointed that the author/illustrator didn't do more with his material.
