One of the most exciting and infuriating books I have read this year is Big Brother by Lionel Shriver (HarperCollins), a very funny, ultra-original tour de force about a woman's relationship with her obese older brother. Loosely based on Shriver's own "big brother" (he died in his 50s), it plays on the "what if?" themes Shriver covers so perfectly. What if you had a sibling in that condition? Is it wrong to intervene? Or wrong not to? It has an extraordinary narrative twist that had me throwing the book across the room in disbelief and reluctant admiration.
Sisterland by Curtis Sittenfeld (Doubleday), the "novel about psychic twins which is not really about psychic twins", is a must-read: it's the best dissection of a life spent among small children I've ever read. Equally original and daring is Claire Messud's The Woman Upstairs (Virago), an extraordinarily brilliant book, fizzing with anger and wit, which reminded me of the energy of Zoë Heller's Notes on a Scandal (even though the ending made me very cross).
For an elegant meditation on war and its impact on family life, Elizabeth Day's lyrical Home Fires (Bloomsbury) comes highly recommended. Meg Wolitzer's The Interestings (Chatto & Windus) is a complex, cleverly interwoven analysis of the moment when the lives of six friends begin to unravel. Mark Lawson's The Deaths (Picador) is a must for anyone who hates their own obsession with Waitrose, a satire on Middle England where "every home is almost a village of its own".
Unexploded by Alison Macleod (Hamish Hamilton) is a quietly poetic deconstruction of a marriage imploding in Brighton during the second world war. Lion Heart by Justin Cartwright (Bloomsbury) is a madcap revision of Richard Coeur de Lion: think The Da Vinci Code for intellectuals. Blood & Beauty by Sarah Dunant (Virago) is a wonderful reimagining of the lives of the Borgias.
And, if you must have another doorstop in the year of the doorstop (after Eleanor Catton's The Luminaries won the Booker), then go for Donna Tartt's The Goldfinch (Little, Brown): a literary page-turner about love, betrayal and the art world. My own 500-pager of choice? Elizabeth Gilbert's The Signature of All Things (Bloomsbury). Don't read anything about it (spoilers are too easy with this novel), just read it. In some ways 19th-century botanist Alma Whittaker sees all life has to offer. In other ways she gets trapped in a binding closet. Hugely enjoyable.
From the Costa shortlist, Instructions for a Heatwave by Maggie O'Farrell (Headline) is a reliably great read, like all her books. This is the saga of an Irish family in London set in 1976. O'Farrell has a wonderful ear for dialogue and an eye for the irritating quirks of domestic life. Far less cheering but just as much of a page-turner is All the Birds, Singing by Evie Wyld (Jonathan Cape), a weird and wonderful novel about isolation, memory and a dog called Dog. It tells the story of a young woman trying to run away from a complicated past. She ends up on an unnamed island off the coast of Britain, tending sheep which keep mysteriously disappearing.
Of all the novels on the prize shortlists, I most loved two books which have been around for a while and are now in paperback. Where'd You Go, Bernadette? by Maria Semple (Phoenix House, shortlisted: Baileys prize), is a dazzling comic novel about a misunderstood architect. It's an eccentric and brilliantly accomplished story with a real screenplay quality to it. Just as funny (and just as American) is May We Be Forgiven by AM Homes (Granta, winner: Baileys prize), a hilariously clever analysis of two brothers. Of the two, AM Homes has more serious aims and her work just gets better. Great stocking fillers. Or get AM Homes's whole back catalogue for a more substantial gift.
