Parasitology titles

[Jim Watson]

I am a sixth year student on the west coast of Scotland, UK and am looking for 
titles towards a upper high school/first year university level.  Living on the 
west coast of Scotland it has been difficult getting information on this 
subject and I would appreciate it If any wisened persons could suggest 
some worthwile titles that are interesting, not too complicated, but not too 
simple, and easy to obtain in the UK. 

I have also been accepted to do volutary work, and am hoping to travel to 
Indonesia, are there any titles which are worthwhile to read on the parasites 
of this area of the world?

Thanking you in advance for your help
