book scavenger is the first book in a series by Jennifer Chambliss Bertman who came up with the idea of combining geocaching and book crossing to make book scavenger. How many people started book crossing after reading the book? I for one did. I thought book scavenger seemed really cool, and i read about the authors idea, and my family started this because that book was amazing. Everyone should read it. Thanks J.C. Bertman!!!
