I'm talking about Suzanne Collins's Mockingjay, of course. The conclusion to The Hunger Games, it's the third and final book in an amazing young adult series that tackles the big questions in love, war, and politics, while the plot gallops along at a breakneck speed, and it came out last Tuesday. If you haven't read them, what are you waiting for? All three are available now at a library or bookstore near you!
Collins is one heck of a writer, and for younger kids, there's her Gregory the Overlander series. Gregory is just a normal kid who accidentally follows his baby sister through a vent in the laundry room of his apartment building and ends up in an underground world populated by violet-eyed people and giant rats, bats, and cockroaches. A mysterious prophecy and plenty of action make these compulsively readable as well.
