Bethany didn't know what to think. Her parents had been acting weird for months-her dad seemed tense, and her mom made a full-time career out of crying. Then one day, they all got in the car and started driving. All day, all night, they drove, so long that Bethany wasn't even sure what state she was in. Then, in some small town, they stopped. Her dad got out of the car and walked up to a house. Bethany had never seen this town before, but her dad seems to know the lady who lived here. She hugged him like he had come back from the dead. Meanwhile, Bethany's mom was crying harder than ever. Bethany eavesdropped on her dad, and heard something about "Elizabeth." Her life was forever changed...and she still didn't know where she was or who Elizabeth was.
Double Identity by Margaret Peterson Haddix was fast-paced, unpredictable, and fascinating. I read it cover-to-cover without stopping, twice, and I still can't believe the ending. This was definitely a great read.
