Utterly charming!
"The Church Mouse" is the first in a delightful series of colorfully illustrated, wonderfully funny books about mice and a cat who live in a church. The books are thoroughly English-y (with a vicar and a vestry and a sexton and choirboys and so forth in the background), but if it doesn't put the parents off, it won't bother the child. My kids adored these books, and so did I.
