Mind Echoes — Leslie O'Kane

MIND ECHOES continues the story of Ellie Montgomery, a Stanford pre-med student whose family members were brutally murdered so that her brilliant mind could be used in an experiment by a corrupt neurologist. Ellie is now living as Alexis Bixby, an artistic high school junior, and she is sent reeling by a sticky-pad note she finds fastened to her backpack. The note-writer also claims to be Ellie Montgomery.

Ellie realizes that her arch nemesis, Dr. Jennifer McGavin, has tracked her down, and is once again willing to destroy anyone who gets in her way. Furthermore, Ellie has to accept that a second person shares her every thought, memory, and experience, and that she now has herself as a rival for her boyfriend's affections.
