Life is an adventure. That’s what their mother always told them. However, thirteen-year old Abigail Link and her ten-year old brother, Quinn, haven’t had much adventure in their lives. They’ve never traveled anywhere. They’ve never done anything thrilling or dangerous…until now. Abigail and Quinn are forced to leave their home, move in with a grandfather they barely know and enroll in a new school – the prestigious Belvedere Academy. Then, the adventure really begins. Abigail and Quinn find themselves in a world of mysteries, riddles and danger – traveling across the United States, searching for hidden clues and uncovering family secrets.
