SOLVED. Book about a witch [s]

[Leen]

YA fiction book about witches / wizards. All I can remember is the beginning of the book. The main character is walking around a book store and her finger gets stuck on a book which turns out to be magic. The book is part of a longer series. I read this around 2003.

Highly likely that it's So You Want to be a Wizard by Diane Duane.
