I remeber this book
Hey man, nice work. Your art was really good. The animation was OK though...to many tweens, there are places where tweens are appropriate but you should try and use frame by frame for things like walking so your characters don't look stiff.
also instead of putting text against a black background it would make it A LOT more interesting if you replaced the black with a drawn background(maybe a view of the camps?)
still, nice work keep it up.
