In no particular order:

'Private Peaceful' by Michael Morpurgo moves me to tears every time I read it.
'The Oxford Book of English Verse' I will never be done with.
The poetry of Donne, Auden, R S Thomas.
Shakespeare!
'The Pickwick Papers' or anything by Dickens delights me.
'Interview with the Vampire' by Anne Rice is just riveting and so sensual.
'Dr Faustus' by Marlowe feasts the imagination.
Any Alan Coren for supreme wit and invention with language. Ditto, PG Wodehouse.
'Gerald's Game' by Stephen King. BDSM gone wrong and the creepiest escape attempt ever.
'Black Narcissus' and 'In this House of Brede' by Rumer Godden. She's a wonderful, insightful writer.
