Barnes & NobleMaking Friends (Making Friends Series #1) by Kristen Gudsnuk

Danielle needs a perfect friend, but sometimes making (or creating) one is a lot easier than keeping one! Sometimes making a friend is a lot easier than keeping one! Sixth grade was so much easier for Dany. All her friends were in the same room and she knew exactly what to expect out of life. Now that she's in seventh grade, she's in a new middle school, her friends are in different classes and forming new cliques, and she is totally, completely lost. What Dany really needs is a new best friend! So when she inherits a magic sketchbook from her eccentric great-aunt in which anything she sketches in it comes to life, she draws Madison, the most amazing, perfect, and awesome best friend ever. The thing is, even when you create a best friend, there's no guarantee they'll always be your best friend.
