I was pleasantly surprised at just how good "Moorland Forensics - Bound by Polaris" was, and how much I thoroughly enjoyed reading it! 
Muriel Jennings, elderly mother and owner of the very successful Jennings Clay Co., has been murdered. She is survived by her children and business partners Stella and Mark Jennings. Can Moorland Forensic Consultants help solve this mysterious and baffling crime. Can a book "The Sinner's Daughter" based on a Dartmoor serial killer from 15 years ago hold all the answers??? 
This was a really intriguing murder mystery book that kept me guessing till the end and I loved the little interesting paragraphs in between chapters eerily relating to the storyline regarding the serial murders. It turns out there is actually two storylines running alongside each other throughout the story which tie together at the end seamlessly and really keeps your interest going until the conclusion. 
James, Fiona and Katie Sinclair are the very intelligent and knowledgeable siblings who own and run Moorland Forensics and are delightfully likeable and engaging characters. The way the author Julie D. Jones incorporated bits of each of their previous private life was very interesting and clever. I can easily see future books delving more into their pasts. 
There's a lot of forensic knowledge covered in the plot and the author must have carried out a huge amount of research to able to describe all the technical equipment and processes involved in forensic science. 
"Moorland Forensics" really is a smashing crime novel that I'd highly recommend and I truly hope to read more about the intriguing cases the Sinclair siblings are given to assist solving.
