UK law allows for quotes when used in certain circumstances such as study. As far as I am aware there is nothing to stop a book being reviewed or a synopsis given. The only thing is, do you want to give away the plot as I am sure others will enjoy the book more if it comes as a surprise.
Nothing to stop you giving brief details of what the book is about and reviewing it.
As for what I am reading, I have quite a backlog. I am working my way throught the Harry Potter's (On number 4, so 3 to go). I have a couple of Bernard Cornwall's to read (a bit formulaic but I love history). I have a couple of Bill Brysons to read and Cormac McCarthy's The Road (if I want to make myself depressed).
For my diploma, I have just finished John Simpsons Unreliable Reports, which should be read out at the Levenson Inquiry as it shows nothing has changed with the British Press (yes, the Daily Mail has always been for the congenitally stupid). I have just started Essential Law for Journalists (yes, the wonders of defamation and the Human Rights Act).
