"Insomniac Shark" (失眠的鯊魚 / Der schlaflose Hai) is a trilingual poetry collection that navigates the fluid spaces between languages, cultures, and identities.

Written in Berlin, these poems reflect on the stillness of a city that never sleeps and the movement of a mind in constant migration. From the "Flow of Time" to "The Rose Braving the Wind," Angela Hsu weaves personal narrative with sharp cultural observation, creating a poetic landscape where the personal becomes political, and the silent becomes audible.
