Justin Bieber's mom penning memoir

GRAND RAPIDS, Mich., March 6 (UPI) -- Pattie Mallette, mother of Canadian pop star Justin Bieber, is writing a memoir, Revell, a division of Baker Publishing Group, said Tuesday.

The publisher said it has acquired the world rights to "Nowhere But Up: The Story of Justin Bieber's Mom." Written in collaboration with A.J. Gregory, with a foreword by Bieber, the book is slated for release Sept. 18.

Mallette's book is to include details about the trauma, abuse and addiction that affected her early childhood and young-adult years. She reflects on her search for love and acceptance that led to teenage rebellion and a suicide attempt at 17, and she recounts the way her life turned around when she found herself pregnant and facing an uncertain future as a single mom, a synopsis said.

"Pattie's story is a powerful example of courage and determination that will inspire anyone who has faced struggles in life," Jennifer Leep, editorial director for Revell, said in a statement. "She's living proof that even in the darkest of places, there is always room for hope."

Mallette will support the release of "Nowhere But Up" with media appearances and speaking engagements throughout the United States and Canada. She plans to donate a portion of the book's proceeds to charity, her publisher said, without providing details on the intended recipient.
