Hello Rick hope the chemo's going well.
You may laugh at this but here is a couple of really good books that I would say are really good
Kane and Able Jeffery Archer Ok laugh but it is really a good book and well woth the effort.

I've also reciently discovered the writer Jeffery Deaver, the books he has done are entertaining and always have more twists than a bag of spiral pasta. Any of the Lincon Rhyme ones I'd thouroghly recommend.

Maybe Trainspotting by Irvine Welsh but it s a wee bit difficult to understand if you cant get into the Scottish Edinburghonian dialect in the written form.

And if you fancy all the Harry Potter books one after the other and youll be hooked like I was. Being a former medic in the army I laughed at my doctor for reading them and he recommended them to me. Not till about 2 years later once I had left(couldnt be seen to be reading kids books you know) I took them up and they were brilliant light and heavy reading.

Hope that you try some of these as they are all worth the time
Dylan
