The Knuffle Bunny books were a gift for my daughter from my brother and his wife. The first book involves a pre-verbal Trixie losing her precious bunny at the laundromat - dramatics ensue. The second book examines what happens when Trixie brings Knuffle Bunny to school and another girl has the exact same bunny - a crisis we can all relate to. The series ends with an overseas trip to visit grandparents in Holland. I won't give anything away but I may or may not have gotten choked up at the ending.
These books are great. I truly don't mind reading them over and over and over and over again. Mostly because I'm totally absorbed in the illustrations while I read them. Mo Willems (author and illustrator) uses photography as a backdrop for his simple, colorful, and funny illustrations. I love the dynamic between the page background, the photographs, and the illustrated people. There is so much attention to detail - the photographs are manipulated to create a simple aesthetic for the background (no wires, no A/C units), shadows are added in under the illustrated characters, and the characters can walk right out of the frame of the photographs making them come to life.
