I've read Paula Daly's first two books - Keep Your Friends Close and Just What Kind of Mother Are You? - and devoured them both in a day. Her new book, The Mistake I Made, was also a one day, lazy day read!
The Girl on the Train is Paula Hawkin's debut novel. And oh, what a debut!!
As Chimney Sweepers Come to Dust
The marco Effect
I tell you, Alafair Burke just gets better and better with every book. (And she was pretty darn good to start with!)
