The Memory Keeper

Eighteen-year-old Natalie Gorman is a mind weaver, able to alter memories, but it is not the life she would have chosen for herself. So when Peter Sheinfeld shows up at her door, a heart-broken young man desperate to have Natalie erase the woman he had loved, he changes everything.
As Natalie decides to take on this near-impossible and forbidden task, a mysterious shadow starts to haunt her, leaving behind odd clues and relics she cannot understand. Even after her best friend, a witch named Piper, insists that Natalie and Peter's sanity is on the line and that she cut ties, it is hopeless. Natalie is already too involved and perhaps falling in love, despite the risks, and with the queen mind weaver on her scent.
When Natalie unveils Peter's true intentions, it is enough to shatter everything, unless she is brave enough to pick up the pieces and look into her own reflection.
