Pirate Treasure of the Onyx Dragon Choose Your Own Adventure Book

Your family tells a story about a shipwreck with pirate treasure aboard, just off the coast from the big, old house your Aunt Lydia lives in. You and your sister Hannah go there for the summer to take a break from your life in Egypt. She won’t talk about the treasure or help you understand clues that you find—maybe the treasure has a dangerous curse attached?
