klinfield answered your question “mightymads answered your question:Calling all Chris Pine…”
“Daring Greatly ” by Brene Brown would be a great choice IMHO.
Is that non-fiction? For some reason I was really thinking of a novel, but all the best options seem to be non-fiction… I’m worried that as a gift it can seem like Zach is making a suggestion for something he finds lacking in Chris, as opposed to something he thinks he’d enjoy, you know? There’s always a chance that a novel could hint that way anyhow, but I’d rather be more subtle. That said, I’m coming up a bit dry, so I will definitely look into this as well. Thanks so much for the suggestion!
