I appreciate the simple complexity (how's that for a contradictory description?!) of this book. The pictures tell the story the words hint at. The things that trip me up about this one is a) its a complex subject presented in a "simplistic" way (for lack of a better word), b) the text would lend itself to be read aloud to a child who probably can't grasp the complexities of slavery or the underground railroad, c) I'm wondering if parents/caregivers/teachers looking for material on this subject will pass it over because it functions so well as a straight-up picture book (not as one of those wordy, didactic types), and d) the book almost needs a companion, whether that be a conversation or another book that explains more of the story. Also, Shane W. Evans' author note at the end... love!
