The Sister (finished)

** spoiler alert ** Ending was weak. Spoilers: Anna is actually Annabelle, Charlie's twin separated at birth. (weak) Both have Marfan syndrome, weak heart and tall. Charlie dies after sprinting (weak heart, weak plot). Annabelle hates Grace because Grace was Charlie's best friend and "sister" when Annabelle should have been. So Annabelle comes back for vengeance. She seduces Grace's beau, moves in, tries to kill Grace a number of times, eventually captures Grace, chains her to a bed, captures her mother, chains her to the same bed. Then . . . Mom picks the lock and Annabelle goes to jail. Grace has a baby though she doesn't (though she may) reunite with weak boyfriend, Dan the Man. Jensen's observations as a writer are excellent. The plot was okay (though Grace seemed stupid in her failure to see through Anna). The ending . . . cover your eyes. Still, I'd read another by Jensen because of her skill as a writer and her powers of observation. This was her first; I suspect that her observation and writing skill will stay the same or improv slightly while her plotting will go way up.
