Grief is the Thing with Feathers is a hybrid of prose and poetic styles about a crow who visits a grieving family of a Ted Hughes scholar and his two young boys. It draws heavily upon Hughes's Crow: From the Life and Songs of Crow and its title is derived from Emily Dickinson's "Hope is the thing with feathers". In 2016, Grief won the Sunday Times PFD Young Writer of the Year Award, the Books Are My Bag Readers' Award for fiction, and the International Dylan Thomas Prize. It has also been shortlisted for the Guardian First Book Award and the Goldsmiths Prize for experimental writing. Reviewing for The Guardian, Sarah Crown writes that the book "is heartrending, blackly funny, deeply resonant, a perfect summation of what it means to lose someone but still to love the world – and if it reminds publishers that the best books aren’t always the ones that can be pigeonholed or precised or neatly packaged, so much the better". It has been translated into twenty-seven languages. Grief is the Thing with Feathers was adapted into a play of the same name, directed by Enda Walsh and starring Cillian Murphy, which premiered in Dublin on 25 March 2019 and has been performed in London and New York. In an interview, Porter details the experience of adapting Grief for the stage: "ith both Cillian and Enda, the goal was to make the production as true as it could be to the book. There were no changed endings or swapping one feature for another". Cillian Murphy won an Irish Times Theatre Award for "Best Actor" for his performance as the grieving father. The play was a New York Times Critic's Pick, with Ben Brantley writing that the performance "beautifully evoke the way in which the whole world seems apocalyptic after a personal tragedy". On 5 March 2019, Porter's second book Lanny was published by Faber and longlisted for the Wainwright Prize 2019 and Man Booker Prize 2019, and has shortlisted for the 2019. Faber describe Lanny as "a story about a family whose village is peopled by the living and the dead. It’s a story about a boy with a gift for friendship and the traces of enchantment he leaves in the closely woven lives around him". The book examines rural English community life and childhood myth in response to social division and ecological crisis. The book is set to be adapted into a film starring Rachel Weisz.
