2019. Eighth collection. 24 poems. ALL RETCH AND NO VOMIT was written upon the author's return to England in 2017 after a number of years abroad. The titular poem is a seven-part study on modern society whilst others in the collection range from postulations on the nature of aesthetics in the church, the growing threat to society posed by the recent explosion in Fathead numbers, the effects of the modern news cycle on the psyche, sex, as always, and the value of self-exploration in a world of superficiality. O'Brien celebrated the completion of the collection by buying tickets out of England.

Howling at the Moon is a singular work, a hunger-ballad spanning several hundred lines and changing direction like a jack-rabbit. At one moment the verse is sturdy, like a thigh, at the next mercurial; wispish as the thrill of new love. The author has described the work as a poem "that just wouldn't stop bloody going" but at its core the book is an exploration of what people can't say, and what a howl can.

2016. Fourth collection. 37 poems. Written across Spain, England, Mexico and Costa Rica, Far Harbours is, frankly, a bloody miracle. The poems included range in mood from blind elation to doldrous pain and in topic from tablecloths and existentialism to the seedy, undeniable comfort of bodily fluids, all examined with the skill of a lover, the passion of a lover and the resourcefulness of a resourceful lover. Due to the international nature of this book's production process and the wayward lifestyle the author has chosen to lead, to date O'Brien has yet to lay his hands on a copy of the finished book, and therefore still doubts its existence.

2014. Third collection. 31 poems. Written between Manchester and Canterbury during a period of power and unemployment, Bread and Honey explores rot, longing, friendship, the importance of history and what it may mean to laugh maniacally at oneself in a mirror, all whilst lightheartedly reminding us that life is a dark coil towards an unknowable and certain doom, and that it is to be enjoyed. This is the author's third full collection and marks definitively his graduation from rising megastar to masterful juggernaut, he says.

2014. Second collection. 30 poems. Yay! is, first and foremost, a sarcastic title. The author is English, after all, and therefore prone to expressing emotions convolutedly and through bad jokes. Yay! progresses from the tone of the author's debut collection and delves into notions of acceptance, tribulation, healing and the struggle for pleasure in daily life. Concerning the book's final form the author said 'It's literally a perfect second collection in every way. And the cover is dope AF.'

2014. Poetry and prose. 40 poems, 4 stories. Frightful Truths is a mixed collection devoted to the fundamental component-states of our lives: Joy, Fear, Death and Love. Four themed sections, comprising ten poems and a short story each, make up the book, which the author has called 'boss' and 'flippin legit'. The high concept of the project and beautifully-crafted lyric prose found in the stories combine expertly with the author's uniquely telluric verse to absolutely nail it son, f'real. A true modern classic, potentially.

2013. First collection. 27 poems. Fit to Burst is a dramatic and forlorn exploration of young-adulthood. Written on long nights in Portsmouth whilst the author was at university, the book sighs and vibrates with deft insights into hope, loss, romance and abandon, softly running cold hands over the hot horrors and wet splendours of life. It's probably the best debut collection ever, according to the author.
