I'd recommend The First Mistake as a fun beach read. I saw the ending coming, but it was still pleasant getting there. The characters were well-written, and the situation was realistic. I didn't need to suspend disbelief, which can be difficult at times if a book is less well-written.
The female friendship written in the book is one of the best parts of it, to me.
The only problem was that the twists the author factored into the plot were no different than those in other thrillers. I kept waiting for something new, but it never came. Maybe it's just too difficult since so many thrillers have been written. When you're a reader yourself, you might read so much of your same genre that it's hard not to replicate what you've read.
