On His Watch by Katie Ruggle is a contemporary romance. This is a quick read, perfect for those with limited reading time. Ms. Ruggle has given us a well-written book and furnished it with a delightful cast of characters. Derek is on the fire department dive team. Artemis is an elementary school teacher. Derek and his team leader arrive at the school to give a presentation to Artie's class. Madness and mayhem arrived right behind them. Artie and Derek's story has enough drama, humor, sizzle, suspense and action to keep any reader happy. I enjoyed reading On His Watch and look forward to my next book by Katie Ruggle. On His Watch is book 0.5 of the Search And Rescue Series but can be read as a standalone. This is a complete book, not a cliff-hanger.
