Books on dealing with suicide of a loved one.

I am searching for recommendations on books on dealing with the grief of a suicide of a loved one.
I would like to read myself and suggest to the family, in the right time.
I am searching for something along the lines of self help, psychology, psychology of death, maybe something esoteric, I am reading the Heaven is for Healing at the moment where they discuss the concept of past life and the soul's journey.

Would be thankful for any suggestions and also how it helped you or someone else.
