Aside from a few detail glitches--some details come from nowhere (stink bug?)--this hums along nicely. Katie is urged by her mom to re-friend a prickly former friend, a preschool classmate, Nora, out of sympathy, since her dad is now working out of town. Nora seems to LIKE having no friends, and isn't positive about becoming a member of the Junior Guides; the after school meetings are made trickier because they have a new leader, whose ideas for change aren't always welcomed, especially by Katie However, when Nora say "pass" on a sharing activity, Katie sticks up for her, and they develop a grudging respect. (So does the new leader, it turns out.)
Plot complications: Nora and Katie are chosen as CO-leaders of the flute section, when Katie had been leader by herself. Nora asks for one of Katie's older sister's toy horses, thinking they're Katie's, and Katie agrees. Now what? Also, planning a sleepover party.
This captures the tricky dynamic of trying to blend old and new friends, and to include people who aren't that friendly. I like that Nora doesn't really change that much: she is funny, and kids come to appreciate that; she does try some new activities, but she doesn't morph into a bubbly buddy. The girls' friendships develop through some misunderstandings, and tough conversations involving telling the truth. Katie's comments and attitudes are funny and perceptive. Her parents are involved and thoughtful.
The frequent drawings add humor and sometimes move the plot, although some were a little too tiny to see/read the details.
Overall, a solid choice for fans of "Diary", with a much more likable protagonist.
