The Invitation by AM Castle
In my opinion... I love a locked room mystery, in the style of Agatha Christie, so was looking forward to this novel where an island 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...
