I picked up Grey Matters on a whim when I saw it on NetGalley and it far exceeded my expectations.
Costello's pieces are full of emotion, unfiltered honesty, and hope. I've lived through every single one of the challenges—depression, anorexia, self-deprecation, and eventual acceptance and healing—and Costello writes from the perspective of someone who has obviously gone through them all.
While many of the poems are only a sentence or two long, they are all beautiful and compelling in their own concise way.
I recommend this to anyone who's ever struggled with self-esteem, burnout, depression, or anorexia.
