Escape From Memory

When Kira agrees to let her friends hypnotize her at a slumber party, she has no idea that she will reveal secrets even she didn't know she had - memories of fleeing a war-torn country with her mother, understanding a language she can't identify. Then her mother disappears, and a woman calling herself Aunt Memory takes Kira to Crythe, a place that doesn't officially exist, in order to rescue her mother - or so Kira thinks. She soon learns that there are memories locked in her mind that place her and her mother in grave danger, but those memories are also the only thing that might save them.
