Frío fatal (Diario de Greg, 13)

When Greg Heffley's school closes due to a massive snowstorm, the neighborhood transforms into a frozen battleground: rival gangs fight for territory, build fortifications, and engage in epic snowball fights. In their struggle for survival, Greg and Rowley must navigate their way through warring factions, forging alliances and betrayals. When the snow melts, will the two friends emerge as heroes? Or will they at least manage to survive this all-out battle?
