Florid

Under the spell of a brutal delusion known to him as the Water Impin, Dudley waits out his days in the confines of a psychiatric unit. When the resolve rises in him to defy his hallucinations, he realises the last threads of his sanity are at risk. -- Described as "deeply moving" by Random House, "well written and compelling" by Penguin, and "very funny" by Harper Collins, Florid is a darkly comic journey through psychosis unlike anything else you will ever have read.
