Sent (The Missing #2)
Published Aug. 25, 2009 by Simon & Schuster Books for Young Readers
I read the first and second books of the series one after the other, and it was a fun read. The second book is filled with history, which I love, but it was a bit confusing. I really just had to push on through her "explanations" and focus on the story. Some inconsistencies, as well, but nothing too distracting.
