Titanic: Unsinkable is the first book in a trilogy. The series is written for ages 8 and up. I happen to love all things Titanic so this story gets a star just for the subject matter, right up front. The book is well written and the story is told through the adventures of four teenagers. Paddy is an Irish lad, running from some notorious gangsters, only to find out they have also booked passage on the very ship that he has stowed-away on. Alfie, an English boy has lied about his age to acquire his job as a steward on the same ship his father works as a broiler man. Sophie and her Mother, who is a woman’s rights activist are on their way back to America. Julianna is the daughter of an earl. She and her father are visiting America on business. The four teens find trouble, mystery and suspense on the Titanic. I enjoyed book one and will be moving on to the next two. I give this book 5 stars.
