Tommy Two Pockets and the Posse of the Marsh starts in 1987 at the fictional Mouillee Rest Home near the Lake Erie Marshes. The Main Character Tommy Two Pockets doesn't exactly get along with the staff and during his downtime, reflects on his time in Black's Bay as an 11/12-year-old boy in 1920, where the Posse of the Marsh is formed.
Black's Bay is a small fishing hamlet on Lake Erie where they are terrorized by the local wood cutter who is confronted by the Posse. It is an adventure story centered around love, loyalty, and a look into end-of-life issues.
If you read POP's and Fricke Island, you will recognize some of the characters in this book. It is the 3rd in the Erie Marsh series. However, it can be read as a stand-alone book.
