The writing leaps off the page...it throws up something so original and striking that it takes up permanent residence in a reader's head

Runt is a bungee-jump plummet from modern sophistication into something lurking below, where fantasy takes flesh and ancient knowledge prevails

Runt deserves the hackneyed description 'tour de force' ... it demonstrates Griffiths, a gritty realist, in complete command of the dark despairing gloop that so often smothers human lives

You would have to go back to Thomas Hardy to find a British writer who evokes a landscape so completely

Evolutionary psychology meets mythology in this short, strange, savage novel... Niall Griffiths's prose enchants you

The troubled teenager's tall tale spills out in a syntax-defying stream of consciousness that is at once liltingly innocent yet seeded with profundity

Griffiths excels in exuberant and experimental portraits of marginals. He does not disappoint with this linguistically inventive portrait

As ever with Griffiths, this is bleak and violent, sometimes bitterly political stuff peppered with absurdly funny moments

[It has a] visionary simplicity and mythic sense of place

Niall Griffiths is unrivalled as the literary voice of contemporary Wales... He mixes gritty realism with myth, poetry and regular doses of bone-cracking violence

A fascinating world, a world of subtle political machinations and fine oratory and nuanced debate, and complex legislation, and intrigue ... Extremely absorbing

as sleek and well-crafted as any classic of the genre...a timeless political thriller

A historical thriller of rare ambition

Vivid, so beguiling ... Lustrum is assiduously researched, and it conjures a trick often missed by historical novels: flavoursome facts give a sense not just of a place and time but of developing lives. Harris remembers that we all exist in our own past and in visions of our future as well as in the present ... It is this concertinaing of history into a series of cogent, life-changing memories that gives Lustrum its concentrated excellence

No one delivers thrilling yet timeless games of power, sex, fame and Rome like Robert Harris.

Robert Harris brings the cut-throat republic to life... He understands politics and how to dramatise them

Harris has replaced John le Carre ... stupendous plots, good characters and lightly applied erudition

Lustrum is a serious piece of storytelling, enormously enjoyable to read, with an insider's political tone which makes the dedication much more than a matter of convention or duty

Harris has taken the DNA of Cicero's great speeches and animated them with utterly believable dialogue...Harris's greatest triumph is perhaps in the evocation of Roman politics, the constant bending of ancient principles before the realities of power, and in his depiction of what it was like to live in the city: the mud, the guttering lamps, the smell of the blood from the temples ... I would take my hat off to Harris, if I hadn't already dashed it to the ground in jealous awe. *****

Gripping ... A compelling narrative, full of plots, murder, lust, fear, greed and corruption ... No writes is better at creating excitement over political theatre

The thrilling pace of the narrative does not let up from start to finish. Lustrum is an utterly engrossing, suspense-filled read

Dripping in detail it brings ancient Rome to vivid life, yet the political intrigue has echoes in today's ruling classes. And while the pace gallops along, the action is reined in just enough to crank the tension up. *****

Conspiracy, betrayal and political upheaval are the keys that turn this brilliantly researched page-turner

For a page turner...I would go for Lustrum (Hutchinson, £18.99) the second volume of Robert Harris's semi-fictional trilogy on the life of the Roman politician Cicero. The oldest stories really are often the best!

Harris is one of the consummate storytellers of the age, a master of narrative who - whatever genre he tackles - delivers books that are definitions of the word compulsive. In Lustrum, we have the mechanics of the thriller applied to ancient Rome, with immensely powerful results

A fine achievement: a hefty, politically serious thriller that effortlessly reanimates the dusty quarrels of Roman government while casting ironic and instructive sidelight on those of our own

Supreme story-telling

Deeply satisfying, impeccably researched and spectacularly topical ... a thriller to die for ... Harris brilliantly evokes Rome on the edge of political chaos through the eyes of Cicero's slave Tiro, who acts as his mater's secretary ... The pace never falters, and the politics are sharply relevant for today

Harris communicates such a strong sense of Imperial Rome - the book is awesomely well-informed about the minutiae of everyday life

Lustrum... was a fascinating world, a world of subtle political machinations and fine oratory and nuanced debate, and complex legislation, and intrigue, and an extremely absorbing one

It is a tribute to Harris's deftness of touch that this book feels so fresh ... he has a lovely dry, debunking style ... Harris writes about the life of politics with an insight rare among historical novelists ... It is as a pure thriller ... wry, clever, thoughtful, with a terrific sense of timing and eye for character

Lustrum offers a great insight into the psychology of political calculation. The story of Cicero's fall from power to the point where even sworn allies close their doors on him offers little consolation over the next few months for our own leader

What a storm it is. The five year period covered by the novel, the 'lustrum' of its title, has some claim to be the most thrilling in the entire span of classical history ... Remorseless it may be; but it is also, as one would expect of Harris, thrillingly paced and narrated. The excitements of a classic thriller, however, are almost the least of the novel's virtues: virtues which derive in large part, from Cicero himself. What grips most about Lustrum is the seriousness with which the political issues at stake are taken, and the vividness of the characterisation: both of which, in large part, reflect the closeness of Harris's reading of his hero's speeches and correspondence

Robert Harris brings the cut-throat republic to life... He understands politics and how to dramatise them.

Offers great insight into the psychology of political calculation

[Lustrum] stands on its own merits as a thoroughly engaging historical novel. Republican Rome, with all its grandeur and corruption, has rarely been made as vivid as it appears in Harris's book. The allure of power and the perils that attend it have seldom been so brilliantly anatomised in a thriller.

Harris never makes his comparisons between Rome and modern Britain explicit, but they are certainly there. And that's the principal charm of his ancient thrillers - their up-to-dateness.

Intrigue and excitement all the way, brilliantly read by Oliver Ford Davies.
