If you like law or political thriller books, like I do, then I think you'll love to read an author called Greg Iles. He wrote an excellent book called 'The Quiet Game', which you can see my review for here.
Anyway, I'd also like to recommend to anyone who doesn't really read law thrillers (because those who do would've probably read a novel by him before) to John Grisham, who not only wrote the fantastic Pelican Brief, but also the great teen law fiction novel called 'Theodore Boone'.
So, there's my thriller recommendations for this Summer!
Enjoy
Ben
