THE 5th WAVE by Rick Yancey

3. Second Ice Age
FROZEN by Melissa de la Cruz & Michael Johnston

4. Biological Warfare
NO SAFETY IN NUMBERS by Dayna Lorentz
How it will end: In a busy suburban mall just like yours, a biological bomb is found in an air duct. Quarantine follows, then sickness and violence. If this is what’s happening inside, what’s going on in the rest of the world?
Who will save us: Among the stranded shoppers are four teens, who all cope in unique ways, form alliances, and try to find safety at a time when adults cannot be trusted.
GRASSHOPPER JUNGLE by Andrew Smith
How it will end: With six-foot-tall praying mantises, the result of a dangerous scientific experiment, running rampant across the globe, eating humans and multiplying.
Who will save us: Austin Szerba and Robby Brees, two Iowa teens who seem to be the only people who know what’s happening. Although, they did accidentally release the “unstoppable soldiers”, too, so…at this point, the world might be beyond saving.
