I'm so sorry for the loss of your son. I just discovered John O'Donohue this year. My daughter received his book "Beauty" as a gift. She didn't read it, but I was curious and haven't stopped reading it since December. I read it in small bites. It's just so gorgeous I need to think about every other paragraph for days. I'll get The Space Between Us next. I'm glad you mentioned it and very glad your sister is there to support you in your grief.
