Alice, a young American on her travels, arrives in the West of Ireland with no plans and no strong attachments - except to her beloved mother, who raised her on her own. She falls in love with an Irishman, marries him, and settles down in a place whose codes she struggles to crack. And then, in the course of a single hot summer, she embarks on an affair that breaks her marriage and sets her life on a new course.

After years working in war zones around the world, and in the immediate aftermath of her mother's death, Alice finds herself back in Ireland and contemplating the forces that led her to put down roots and then tear them up again. What drew her to her husband, and what pulled her away? Was her husband strangely complicit in the affair? Was she always under surveillance by friends and neighbours who knew more than they let on?

When Light is Like Water is at once a gripping story of passion and ambivalence and a profound meditation on the things that matter most: the definition of love, the value of family and the meaning of home.

'Adultery is often sentimentalised in fiction, but in her ferociously well written second novel Molly McCloskey gives it to us straight ... Each brilliant vignette offers a new angle on Alice's ballooning sense of disorientation ... In spite of its lyrical title and exquisite prose, When Light Is Like Water is a brutal examination of sexual self-delusion. But it also has much that's memorable to say about love - not the affair kind, but the real thing... McCloskey writes with shattering insight on loss and the way that it can make us feel tender towards the world' Guardian

'Powerful ... When Light Is Like Water is a tender depiction of love and loss that combines the personal pull of a memoir with the precision of a short story ... McCloskey's novel is packed with wisdom, and never heavy-handed with it. The details of the affair and the tawdry aspect of forbidden desire are brilliantly related' Sunday Times

'McCloskey describes everything with a luminous exactitude ... It's entirely beguiling' Mail on Sunday

'A thoughtful meditation on connection set against the backdrop of a world on the move ... Though McCloskey has no shortage of ideas, she also engages the heart: she's particularly good on the contrariness of our desires ... Fans of Anne Enright will find much to admire and enjoy.' Daily Mail

'Luminous' Irish Times

'McCloskey has the observational eye of the outsider, able to pinpoint the intricacies and mannerisms of the Irish people and landscape. ... But the writing's the thing. Oh, the writing. McCloskey is the master of the metaphor, the doyenne of the deceptively simple sentence. ... Hers is a wondrous turn of phrase, and yet somehow it makes Alice's life and interiority seem all the more real' Sunday Business Post

'A delightful fish-out-of-water account stitched together with gentle yet wondrous prose' Irish Independent Books of the Year

'When Light is Like Water is as gripping as a memoir and as intimate as a poem. Molly McCloskey has written a novel that is both urgent and reflective, a tender and unsentimental exploration of love's dark corners. It is brilliant: her finest book yet.' Anne Enright

'Molly McCloskey's prose has such immense authority, precision and seriousness. This shimmering, beautiful, restless work will stir recognitions without seeming to try. If you've ever fallen in love with someone you shouldn't have fallen in love with - as who hasn't, once or twice
