Raider's Ransom by Emily Diamand
This book takes place in a post-apocalyptic future, when the oceans have risen, drowning most of the United Kingdom and hurtling humanity back into a more medieval society where only hints and scraps of high technology remain. It follows Lilly, on a quest to rescue the daughter of the prime minister from the Viking-like Raiders, and Zeph, the son and heir to the Raiders' leader. Exciting, fast-paced, and a little haunting when you recognize pieces of our world in the wreck of theirs.
This ten-book series for teen girls is screamingly funny, and will destroy any notions you ever had that the Brits lack a sense of humor. Georgia Nicolson is fifteen, and therefore impulsive, irreverent, often snarky, and terminally confused about who she is and what she wants.
Lost and Found by Shaun Tan
This collection of three Australian short stories are odd, eerie, and thought-provoking, and when paired with Tan's brain-bending collage-style illustrations, makes this a book you won't forget in a hurry.
