Sapphyre (Charmed Adaments #2)

Jamie Starling has no past. Apart from recurring dreams she has no memory before waking in a thick wood, until Rhye suddenly appears, a boy claiming to know her. She discovers that, like him, she is a Sapphyre with magical abilities and must join Rhye and the others against a group known as the Seekers, intent on destroying them all. Jamie finally feels like her memories are starting to return when it is discovered that she is part of a prophecy, and that her powers are far greater than she first realized. She soon becomes the Seekers' new target...but not for the reasons everyone thinks.
