I chose this book to read from Rosie Amber’s Book Review Team book list.

This second book in the series can be read as a stand alone, but to get the full effect and understanding of the story I do recommend reading the books in the correct order. 

Having dealt with Vokkel in the last book, our team of ghost killers are confronted by a new and devious enemy in the shape of a seventeenth century muskateer and a teenage boy. As they unravel what they can about this dangerous duo they become aware an old enemy is lurking in the wings for revenge, which he hopes to gain by unleashing a huge amount of evil as per an ancient prophecy.
The narrative in this second volume is crisper and more concise giving this thriller a brisker pace than the first. We learn more about Billy’s mother and the truth about her father too. 
The book starts in the midst of a big show down and ends with one. I found the unravelling of clues in this thriller fascinating and could not put this book down. I look forward to reading the next one in this series of supernatural thrillers. This book is available to read for free to Kindle Unlimited subscribers.
