Have you ever noticed how so much can change in so little time? That’s how Ruthie feels in I Know you Remember by Jennifer Donaldson. Ruthie Hayden never thought her life could change so dramatically in a matter of seconds until her mother died. After her mothers tragic death, she was forced to move back to her old town: Anchorage, Alaska after three long years. She is shocked to find out when she arrives back to her now sober father, that her long time best friend, Zahra Gaines, is missing. Thinking she was the only person who really knew Zahra, she set out to find her only to realize she may not know her best friend as much as she thought.
