John Adam Wasowicz, author of the Mo Katz mystery series, will be signing copies of “Hazel Falls,” the sixth book in his series, at Winchester Book Gallery on July 1. The book features ‘Hazel,’ a boring device that is currently digging an underground tunnel in Old Town Alexandria to connect water pipes to the city’s treatment plant. Wasowicz began the series in 2017 and has visited the Gallery following the publication of each book. If you’re a fan of the series, join us!
