I thought it would be good to have a thread to recommend books that you've enjoyed that are available for free or less than say £2. I get the daily email but haven't really been that inspired by much on there.
I'll start:
I'm currently reading The Penal Colony by Richard Herley. It was free. It's quite dark but very gripping so far.
I also enjoyed The Baby Thief by L J Sellers which is £1.92. Easy reading thriller, and Stealing Faces by Michael Prescott which is £1.32.
