K-Gr 1 -In Carlson's third book about Henry and his adventures, the mouse has just spent his first day in first grade and is not quite sure how he feels about it. However, as he describes his experiences to his mother, he realizes that for every negative (he doesn't sit near any of his old friends) there is a positive (he's made a new pal who likes soccer and spiders as much as he does). By the time he's finished with his recitation, he's excited, happy, and proud that he's "a real first grader now!" Children taking this monumental step will sympathize with Henry's uncertainty and be reassured by his adjustment. The vibrantly colored illustrations and the cast of animal characters have lots of child appeal. Librarians will particularly appreciate the page where Henry and his classmates are eagerly investigating the "Everybody Books" in the school library. Whether used for storytime or independent reading, the book is sure to find an audience. Grace Oliff, Ann Blanche Smith School, Hillsdale, NJ
