Still See you Everywhere by Lisa Gardner.
In my opinion... I really enjoyed this book, it was set in a location (near Hawaii) that I knew little about , it featured crabs, a lot...
...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...
