This was another thrilling read in the Billie Carlson series, one I highly recommend and one of my favourites. Billie has been successful in her search for Lucas, her missing son, and life is slowly getting back to normality for her. I like the characterisation, it's well described and with excellent development. The plotting is very topical, illegal migrants, and I love that it is set in Glasgow. The pacing is fast throughout, making this another 5* read from the author.
