Bear and Mouse are back, and Bear does not want to go to the library. He is quite sure he already has all the books he will ever need. Yet the relentlessly cheery Mouse, small and grey and bright-eyed, thinks differently. When Bear reluctantly agrees to go with his friend to the big library, neither rocket ships nor wooden canoes are enough for Bear's picky tastes. How will Mouse ever find the perfect book for Bear? Children will giggle themselves silly as Bear's arguments give way to his inevitable curiosity, leading up to a satisfying story hour and a humorously just-right, read-aloud library book.
