While I appreciate the story, and the art and backmatter are wonderful, and the connection of Native stories with whale migration, I do hesitate as I don't believe the author/illustrator is a member of a Native Nation, which leads to concern about whether there is authenticity & accuracy to the tale she created. I did find the below in an article about her for perspective: 

"Caroll Simpson agrees that some stories of tribal or family history are owned by individual First Nations, but she contends that her two books with aboriginal characters are entirely her own making.

'My hope is to stimulate the curiosity of children of all ethnicities to reach further into the study of The First People,'; she says. 'In doing so they will gain understanding and respect for this art and culture here, on this land, that came before us and is renowned worldwide.'"
