Several of Rae Carson's books have been recommended as staff picks at my library. Walk on Earth a Stranger was a good read, not necessarily light, but I enjoyed it nonetheless. I used to play a lot of Oregon Trail as a child; this brought that game to life. It had all my favorite YA elements as well....a little bit of fantasy here, some travel and adventure there, a love story. I'm sorry I will have to wait for the second and third installments. I will pick up other books by Carson in the meantime.
