Intricately wrought, passionate and fascinating... A late masterpiece

In Indignation, his power and intensity seem undiminished

He is a writer of quite extraordinary skill and courage

I relished Indignation. Roth writes with his trademark drive and fluency, on the knife blade between rage and laughter

Roth reasserts his fictional mastery with a fine taut narrative about the frustrations of youth...every part of it is dovetailed into a story of compelling economy...a mid-20th-century tale of nemesis with all the intellectual and imaginative force of a great novelist writing at the height of his powers

A gratifying novel... Indignation is, unquestionably, seriously "good" Roth

Roth's novels abound in comic moments, and so does Indignation...His powerful new novel seethes with outrage...a deft, gripping, and deeply moving narrative

Indignation ought to be required reading for presidential candidates

Indignation is, among its many pleasures, a controlled expression of wrath

If I had to choose one word to sum up Indignation I'd go for classy. If were allowed two: very classy

It takes courage to write a novel about two of Britain's best-know poets - John Clare and Alfred Lord Tennyson - and their encounter in an Epping Forest asylum. It takes skill to turn that into an engrossing, beautiful novel. Foulds has shown both

Rich in its understanding and representation of the mad, the sane, and that large overlapping category in between

Every character, every narrative strand is stunningly written, making it an engrossing and unusual historical novel

The world he evokes is conjured up with remarkable intensity and economy of means

The novel is most notable for its savage descriptions of rural life

Foulds does a marvellous job of evoking the atmosphere of the forest. His prose has none of the awkwardness one often encounters when real-life characters are brought into play

With its unflinching look at treatments of madness, and its authentic period feel, this is an appropriately disturbing, while also beautifully written, story of human endeavour - and human failure.

Chosen in The New Yorker Books of the year 2010: 'An intricate homage to two nineteenth-century poets'.

The funniest writer ever to put words to paper

The greatest comic writer ever

P.G. Wodehouse wrote the best English comic novels of the century

Sublime comic genius

You don't analyse such sunlit perfection, you just bask in its warmth and splendour
