Except for a few minor grammatical mistakes, such as a missing article (the letter "a" and the word "the") this book was very well written. Explosive Situation is the 4th book of a 9 book series. The first 3 books came out on April 1st, May 1st, and June 1st. You need to read from the beginning of the series, because if you don't, you will miss a lot of critical information. In fact, you should read the entire True Blue K-9 Unit series that was published in 2019 BEFORE reading any of these. Both sets of series occur in New York: True Blue K-9 Unit happens in Queens, New York and True Blue K-9 Unit series occurs in, well, Brooklyn, New York. The Brooklyn series makes mention of some of the stuff that went on in the 1st series. Also, there was a prequel to the 1st set of books, titled Shield of Protection by Dana Mentink; followed by books 1-9: Justice Mission by Lynette Eason, Act of Valor by Dana Mentink, Blind Trust by Laura Scott, Deep Undercover by Lenora Worth, Seeking the Truth by Terri Reed, Trail of Danger by Valerie Hansen, Courage Under Fire by Sharon Dunn, Sworn to Protect by Shirlee McCoy, and True Blue K-9 Unit Christmas (2 novellas) by Laura Scott and Maggie K. Black. THEN start reading the True Blue K-9 Unit: Brooklyn series of 2020. As far as I know, there is no prequel to the 2020 series, so you would begin with Copycat Killer by Laura Scott, Chasing Secrets by Heather Woodhaven, Deadly Connection by Lenora Worth, and Explosive Situation by Terri Reed. There is an error on the Kindle edition AFTER you finish reading Explosive Situation. It says the next book is about Belle Monterra; however, that book is either the 2nd or 3rd of the series, not the 5th. Continuing with the Brooklyn series, book 5 will be Tracking a Kidnapper by Valerie Hansen (publication date August 1, 2020); Scene of the Crime by Sharon Dunn (pub. September 1, 2020); Cold Case Pursuit by Dana Mentink (pub. October 1, 2020); Delayed Justice by Shirlee McCoy (pub. November 1, 2020); and True Blue K-9 Unit: Brooklyn Christmas (2 novellas) by Laura Scott and Maggie K. Black. It really is important to read all of these books in chronological order because of the storyline throughout. The killer of the first set is not found out until the next to the last book in the series. Good reading, y'all! Barbara Kelley
