I'm gonna go ahead and say it: best YA series since Harry Potter, and Collins delivers an ending and an epilogue better than Rowling did. She actually managed to surprise me with a couple of twists, and more importantly, she made me keep turning pages because I
cared what was going to happen next.
Okay, it's still YA so the story is not as complex as you'd expect from an adult SF novel, and there were a few plot devices that made me grimace a little, but overall, this was a satisfying read with genuine resolution in the climax.
