I really liked this book. It's split into 2 parts. The first part went back to the 70's, when Petra and her friend Sharon were huge David Cassidy fans. I really enjoyed reading this part, and felt like I was transported back in time to junior high. The second part had Petra and Sharon as adults in present time. I didn't relate to this part as much, but it was still a good read. I Think I Love You had interesting characters and themes, and I would recommend it to anyone who was a teenage or preteen girl during the 1970's.
