NEW YORK (AP) — The mother of Columbine High School shooter Dylan Klebold is planning a memoir in which she will confront the “indescribable grief and shame” she has lived with since the 1999 tragedy.

Crown Publishers told The Associated Press on Tuesday that it had acquired a book by Susan Klebold, saying she was compelled to share her story after the murders at Sandy Hook Elementary School in Newtown, Connecticut, and other schools. The book is currently untitled and does not have a release date. Klebold will donate any author profits to mental health research and charitable organizations.

Dylan Klebold and fellow student Eric Harris killed 13 at the Colorado school before killing themselves. Susan Klebold has previously described her feelings in an essay for Oprah Winfrey’s “O” magazine and in interviews for Andrew Solomon’s book “Far from the Tree.”
