My God what a brilliant read. Robert has done it again. In Erika he has created a character who is flawed, driven and is like a dog with a bone between its teeth. She never lets go. She digs and digs until all the pieces are uncovered and the puzzle put together. If you like your books fast paced and with a satisfying conclusion, then is the book for you. Five stars from me. Thanks to author, publishers and NetGalley for the ARC.
