This is not a bad story but it's impact is severely reduced because it is so badly written. It is badly written because:
-the spelling and grammar are dreadful. In some places, the author manages to write in two or three tenses in the same sentence. Misspelling include "alter" for "altar" and "Menai Straights" instead of "Menai Straits", but examples are numerous;
-the dialogue is clunky in the extreme;
-the author is British but uses too many Americanisms. For example, he always refers to the trunk of a car rather than the boot, ass rather than arse and always uses airplane instead of aeroplane;
-there is no variation in certain words or phrases. For example, a characters always "exits" a building or car and no synonyms for this are ever used;
-every character, however minor, has a detailed back story which adds nothing but detracts from the flow;
-there is too much extraneous information, some of which is repeated many times. For example, I lost count of the times we were told that Liverpool Cathedral has the highest and heaviest bells in the world.
-there are factual inaccuracies too many to note;
-there is over- and unnecessary description. For example, "Mustapha lived near to the town of Holyhead, which is the largest town in the county of Anglesey in the north west of Wales". Invariably he refers to "the island of Anglesey" when Anglesey would suffice.
I could go on. What this book needs is a good editor to remove all these issues.
