The Long Weekend by Gilly Macmillan
In my opinion... A roller coaster of a thriller- I loved the set up, though not so keen on the characters, but regardless found this...
...which is about evenly matched- though my book habit is a little cheaper & easier to indulge on a train in a morning!
I am renowned amongst family & friends for having a book or kindle with me, just in case...I have been reading since an extremely early age - thanks to Mum and the "teach your baby to read" philosophy...
