"Yoon uses the drama of the page-turn beautifully, typography is employed creatively, and the book is perfectly paced. . . . Open the door to this spectacular book and go right in." --The Horn Book (starred review) Dad's office is off-limits--which only makes it more intriguing to his curious young daughter. As soon as she sees an opening, she sneaks in to have a look around. After all, there's no harm in just looking, right? What she discovers is a magical wonderland of sticky tape, paper clips that make glorious strands, and a kaleidoscopic array of sticky notes. Who could possibly resist playing with those? In a joyful ode to office supplies, Helen Yoon leads a celebration of just-for-once breaking the rules--and offers a final, funny nod to adults who harbor a similar urge.
