This book came to be because my daughter had a very clear vision for her next read: a thrilling mystery-detective tale, complete with fantastical elements and a touch of magic. I couldn't resist bringing her request to life. Hopefully you'll enjoy it as much as she did! Thirteen-year-old gaming enthusiast Cassie Summers figures her summer with Grandpa in Edmonton is doomed to be boring. But when she stumbles onto a real-life adventure, boredom quickly becomes a distant memory. What starts as a quaint treasure hunt connected to Edmonton's fur-trading past rapidly intensifies as dangerous characters join the chase for the same elusive prize. Good thing Cassie's got her martial arts moves and a brand-new ally in local girl Mina, because her summer is about to get a whole lot more exciting-and perilous.
