When We Were Alone is an incredible work of art and is very highly recommended.

...Robertson handles a delicate task here admirably well: explaining residential schools, that shameful legacy, and making them understandable to small children. It's a dark history, and the author doesn't disguise that, but he wisely focuses the grandmother's tale on how, season by season, the students use creativity, imagination, and patience to retain their sense of identity. A beautifully quiet, bold strength arises from the continued refrain "When we were alone" and in how the children insisted on being themselves. Flett's gorgeous, skillful illustrations have a flattened, faux naïve feel to them, like construction paper collage, a style that works perfectly with the story. She nicely contrasts the school's dull browns and grays with the riotous colors surrounding Nókom and gets much expression from her simple silhouettes.

Spare, poetic, and moving, this Cree heritage story makes a powerful impression.
