Winter, by Marissa Meyer

This, the final installment of the Young Adult science fiction/fairy tale series, the Lunar Chronicles, is a romping good time. Romance! Action! Villains! Redemption! "Winter" is everything you want it to be, fun to the core and full of the requisite twists and turns, with a great happy ending. Strong female characters (on both sides of the good/evil spectrum) nonetheless have very real emotions and weaknesses. You can be brave and shy at the same time, crazy and courageous, determined and unsure. This is a fabulous series for any teen who isn't ready for more serious science fiction, particularly girls, and for those who enjoy the recent takes on age-old fairy tales. I look forward to recommending this series for a long time to come.
