The memory of forgotten things

"Twelve-year-old Sophia has never told anyone about her unusual memories--snapshots of a past that never happened. She becomes convinced that the upcoming solar eclipse will grant her the opportunity to make her alternate life come true, to enter a world where her mother never died. With the help of two misfit boys, she must figure out a way to bring her mother back to her--before the opportunity is lost forever"--Provided by publisher.
