The Traitor by Ava Glass
In my opinion... I'm always concerned when the book I'm reading is not the first in a series, but I needn't have worried, this novel is...
...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...
