The half life of Molly Pierce / Leno, Katrina

For all her seventeen years, Molly has gone to bed and woken up with few if any memories from the previous day, forced to reconstruct bits of her life she has forgotten. Now, though, she is beginning to remember, and finds that she has engaged in a relationship she doesn't want to forget, but cannot remember.

"Molly, a seventeen-year-old girl who suffers from dissociative identity disorder, has played host to Mabel, a completely distinct personality, for most her life. When Molly faces a crisis Mabel doesn't know she can handle, Mabel lets Molly in on her secrets"--provided by publisher.
