I've tried a couple of Devla Murphy's books & just can't see them thru' to the end:in fact a couple of chapters is enough for me.
ymmv
I seem to remember enjoying
Cameroon With Egbert...
There's something I read that was free on Kindle when I first got one, that seemed like a three-year-old's attempt to write something like a novelisation of
Lock, Stock... It's the only thing I've ever removed from my device because it made me shudder whenever I saw it in the virtual library, so I can't remember its name. That's the only book that's come close to the aforementioned
Battlefield Earth for sheer awfulness.
