Are you thinking of Motherless mothers: How motherloss shapes the parents we become by Hope Edelman?

Same author also wrote: Motherless Daughters: The Legacy of Loss, Letters from Motherless Daughters, and published this year, The possibility of everything.
YES!! that's it!! - the one i read (when i was 12) was Motherless Daughters! and i knew the author (i kept thinking her name was Eden ) had written another one aimed at mothersless mothers.

Thank you so much for that Marydean much appreciated!
