"So, in the summer, we will be going to...... San Francisco!!!!!!!!!!" That was the sentence that changed Thea's life as she knew it, forever. She just didn't know it then. Meet Theodora White, more commonly known as Thea, a tomboyish thirteen-year-old teenager who lives in Philadelphia with her fourteen-year-old brother, Carl and her eleven-year-old sister, Bella. Thea stumbles upon a picture which could change her entire world, only if she recognizes the people in it. A man, woman and a child. She doesn't. Yet, memory tugs the back of her mind. She experiences nightmarish flashbacks, which always have a house on fire, before she wakes up. On a seemingly harmless family vacation, she sets out to find the mysterious people in the picture, with help from Carl, of course. How much have her parents hid from her? Can she handle the truth? A picture. A memory. A house. A fire. That's enough to change everything.
