first of all, the cover was not the author's choice.
"It is clumsily and unengagingly written" - NO, solid grammar, variety of vocabulary
"with countless childish references to sex" - WRONG address, go and read your playboy
"written by a Rome-obsessed adolescent girl" - NO, CmC is an adult neurologist
"if you want to read historical fiction about Rome, I can thoroughly recommend any book from the 'Eagle' series by Simon Scarrrow" - WRONG period (imperial Rome)
"or if it's a factual account you're after, 'Ancient Rome: the rise and fall of an empire' by Simon Baker is utterly gripping" - OR, better, watch the BBC-series.
