The youngest sister of actress Glenn Close is working on a memoir about her struggles with mental illness.

Grand Central Publishing announced Friday that Jessie Close's "Resilience" is scheduled for release in January 2015. The book will be co-written by Pete Earley, author of the 2006 book "Crazy," about his son's struggles.

Glenn Close will contribute three "vignettes" about her sister and an epilogue. She will also narrate the audio edition. Jessie and Glenn Close are two of four siblings.

Jessie Close has been diagnosed with bipolar disorder and has made public appearances with her sister to discuss mental illness. Glenn Close is the co-founder of Bring Change 2 Mind, a nonprofit organization with a mission to "eradicate the stigma and discrimination surrounding mental illness."
