Struggle is universal. But talking about it? Well, that's not always encouraged - especially when those struggles involve mental illness.

Grey Matters is a poetry collection that urges us to have conversations about the things we're told to suppress - to bring our darkness to light. It provides refreshingly honest and relatable depictions of anxiety, depression, and eating disorders while also offering sparks of hope to readers - healing may not be a linear process, but over time, it is possible. Things aren't always black and white: Sometimes, the very thing you're fighting (your own mind) can also be what saves you.

Hundreds of thousands of fans across TikTok, Instagram, and other social media platforms have resonated with Costello's poetry and her ability to depict familiar feelings in new, striking ways. Grey Matters is her debut collection - if you enjoy reading poetry that leaves you feeling understood, comforted, and inspired, this book is for you.
