Synchronicity (Book One of the Geminae Duology‪)‬

What if you woke up in someone else's life?
Hazel Stone is just an ordinary teenager--or so she thinks. But lately, she's begun mind-hopping into a stranger's dark reality, and she's starting to question everything, including her own sanity. Then she meets Max McCormick, the brilliant new kid in town with an impressive list of phobias. A bizarre series of coincidences brings the two of them together, and their lives take a sharp turn from the mundane to the metaphysical. It's up to them to uncover the truth buried in the Stone family history. The more Hazel sees, the less she understands--and the closer it brings her and Max to mortal danger. Will she harness the extraordinary gift she has inherited to find the answers before it's too late?
