Brownstone (2024)

Brownstone (2024) by Samuel Teer and Mar Julia is a YA/teen graphic novel from Versify and HarperAlley, and has received starred reviews from Kirkus and Publishers Weekly, as well as being nominated for a Harvey Award for best YA Graphic Novel. Brownstone was awarded the 2025 Michael L. Printz Award for Excellence in Young Adult Literature from the American Library Association.

From Harper Collins:

"An exciting teen coming-of-age epic from author Samuel Teer and debut graphic novel artist Mar Julia, Brownstone is a vivid, sweeping, ultimately hopeful story about navigating your heritage even when you feel like you don’t quite fit in.

Almudena has always wondered about the dad she never met. Now, with her white mother headed on a once-in-a-lifetime trip without her, she’s left alone with her Guatemalan father for an entire summer. Xavier seems happy to see her, but he expects her to live in (and help fix up) his old, broken-down brownstone. And all along, she must navigate the language barrier of his rapid-fire Spanish—which she doesn’t speak.

As Almudena tries to adjust to this new reality, she gets to know the residents of Xavier’s Latin American neighborhood. Each member of the community has their own joys and heartbreaks as well as their own strong opinions on how this young Latina should talk, dress, and behave. Some can’t understand why she doesn’t know where she comes from. Others think she’s “not brown enough” to fit in.

But time is running out for Almudena and Xavier to get to know each other, and the key to their connection may ultimately lie in bringing all these different elements together. Fixing a broken building is one thing, but turning these stubborn individuals into a found family might take more than this one summer."

A Way To Be, featured in the Harbor Wetland at the National Aquarium

Harbor Wetland is a free, outdoor exhibit at the National Aquarium in the inner harbor. A floating dock and a re-creation of the salt marsh habitat of the harbor before it was developed houses an exploration of the past and future possibilities of the harbor and our relationship to it, while also featuring a multi-media installation comprised of several artists from Baltimore. A mural, soundscape/musical pieces, and an installation of three sets of illustrations represent each individual artists idea of the Harbor Wetlands.

A Way to Be considers a future where our relationship to our city and its environment is one of treating it as if it was another community member, starting on a personal level and zooming out as the set progresses.
