|Then You Were Gone by Lauren Stransick|
In her search for what really happened to Dakota, Adrienne seems to ruin or severely strain almost all of her relationships. She puts her boyfriend to the side, and won't listen to her current best friend's advice. She develops feelings for Dakota's boyfriend, (if he can be called that) and acts on those feelings. She also starts smoking, skipping class, and participating in other behaviors that were not part of her life before Dakota disappeared.
All in all, not my cup of tea. Adrienne annoyed me and I didn't develop any sympathy for her. I did not really care whether or not she found Dakota. When she does find Dakota, the reason for her disappearance is so unsurprising, as is the aftermath of Dakota returning home. I was glad this book was a quick read, because I was ready for it to be over.
