This book, for young of all ages, has a way of crossing genre lines. It's part mystery, somewhat historical, with a latent love story and an element of adventure. The story takes place in Louisbourg, Nova Scotia, which is still Canada's most visited historical site. This one summer, five bad actors arrive in Louisbourg for an unknown reason and our three teenage heroes immediately become suspicious. Once the teens find out why these hoodlums arrived in Louisbourg, finding no help from the police, they set out to ruin the crooks' plot through brave and heroic deeds before the police finally come to their aid. And now it's yours to enjoy.
