Author: Chandra Stafford

Genre: Science Fiction / Mythology
Time travel, bit of romance, a lighthouse, dinosaurs, a cave, library research, a diner, missing dad, worried mother, Greek mythology, and last but not least pirates. That wasn't even last to be honest. But if you're curious, all of the above make their way into this story. If you are intrigued, pick up this book. It's absolutely wonderful. Even has a bit of romance.
