Request #553 From Sui

I used to borrow this book from the library’s kids section. I have no idea what the title is but the author’s surname started with either a letter A or B. There were nice illustrations in the book, depicting brown bears. Story-wise, I vaguely remember a scene where the father bear passed away (maybe) and there was a huge progression in a snowy landscape. That is all I know. Let me know if this sounds familiar!
